World renowned for their work building race winning pistons, Wiseco utilizes
experience from a diverse background of the most sophisticated engines
in such venues as Formula 1, Indy Racing League (IRL), NHRA Pro Stock,
Moto GP, AMA Superbike, AMA Motocross and Supercross to design and
manufacture the highest technology pistons available.

1 Valve Pocket designs that allow maximum flow around valve, also allowing
oversized valves and high lift cams to be utilized.
2 Piston Crown shapes designed to promote maximum Intake Charge
ef ficiency through scavenging mixture “Cross Flow” during intake and
exhaust valve overlap. More fuel and air equals more horsepower!
3 Piston Domes designed for optimal quench during the compression/
combustion cycle, resulting in re sis tance to det o na tion and preignition. The end result is longer engine life and increased horsepower
potential.
4 Precision machined ring grooves with proper orifice/accumulator volume
feature calculated groove root diameters and axial widths, providing
excellent surface finish and flatness, maximum ring seal and minimized
blow-by and oil consumption.
5 World class, ISO Certified, forging facility that utilizes the latest
technologies - Featuring complex forged shapes, advanced materials,
and feature-aligned grain flow technology.
6 Complex Piston skirt profiles that reduce power robbing friction, yet
promote stability in the bore for optimum ring seal.

Skirt Coating
Wiseco’s new ArmorGlide skirt coating is the result of testing, development, and benchmarking through our in-house dyno program. The outcome - minimized friction, maximum
horsepower, and improved wear resistance.
Not only is ArmorGlide a high-tech lubricant that reduces friction, but it also allows the
piston to be fitted tighter within the bore than a non-coated piston. Better ring seal reduces
noise from piston rock. ArmorGlide is being applied to selected pistons.

LS Se
As the leader in LS-1 forged pistons, Wiseco pulled out all the stops when designing
the LS Series. These pistons are designed to accommodate the reluctor ring on
stroker cranks without having to notch the pin bosses.
Offset pins like O.E. and skirt shapes specifically designed for street applications
make these the best available. They have been tested successfully in the highest
horsepower applications.

the GFX ring package and gas
ports reduce friction for noticeable
increases in power.
• Extra deep valve pockets and a
thicker deck allow for higher horsepower, bigger cams, and more
radically milled heads.
• Skirt coated for lower friction,
reduced noise, and superior life.

• The Max 23 Series is the first to utilize
2.250 pin forging technology. The
narrow spacing between the bosses
increases bearing area and reduces
unsupported crown area. This
reduces ring groove distortion and
adds the strength needed to hold up
to the power created by the best 230
heads.

excellent wear properties.
• Anti-detonation Grooves help keep the top ring
groove free of carbon.

are the best available. Contoured
domes and other special features,
along with a dedicated forging,
ensure more than adequate thickness
for the highest horsepower.

• Designed to be the lightest on the
market, the generous Valve Pockets
are compatible with all but the most
milled cylinder heads. Full round
2618 forgings and a newly designed
skirt shape keep piston rock to a
minimum and ring seal at a maximum.
Precision tolerances make these
pistons unbeatable.

Wiseco Quick 16 pistons are designed to fit conventional heads from today's leading manufacturers.
Wiseco Quick 8 pistons are designed to allow for additional flycutting as necessary. Domes that can be cut to a
lower rise to tune volume for different combustion chamber volumes. Every 2.76 grams off dome/valve pockets = 1cc
volume.
• New skirt coatings use Wiseco’s proprietary ArmorGlide™ material (Superior to graphite or Teflon based formulas).
Benefits include - longer engine life, increased horsepower, noise reduction, and much tighter dimensional
tolerances than typical spray-on coatings. Controlled curing processes guarantee the best possible results.
• Designed with input from today's leading edge engine builders and Pro Stock technology to fill the demands of
today's big valve, big cubic inch Sportsman Series engines.
• Configured to maintain proper flame travel and desired compression ratios needed for today's extreme horsepower
engines and exotic fuels. Generous valve pockets for all popular heads and high lift cams
• With the ability to produce dedicated forgings in house, Wiseco is able to design pistons with the lightweight
extreme durability that is expected in a modern day race engine. Fortified pin bosses, maximized ring lands,
dedicated skirt shape designs to minimize piston rock, and reinforced deck and pockets, all add up to handle the
shock loads of modern day power adders
• Vertical Gas Ports located away from valve pockets.
• Oil reservoir below oil drainbacks allow the lower rail to act more efficiently for optimal oil control.
• Ring packages incorporated to handle the highest cylinder pressures and temperatures.
• In stock availability of kits and singles keeps you racing all season.

• Machined from Wiseco sleeve
forgings to offer the same toughness as Wiseco's forged pistons.
• Hard anodized and Teflon coated
for low friction and prolonged wear
resistance.
• Sleeves have a smooth radius that
tapers down to the specific bore
size.
• Compresses the piston rings
smoothly and evenly.
• Greatly reduces the difficulty with
installing thin high-performance
oil rings.

World renowned for our work building race winning pistons, Wiseco utilizes
P

c
Ra
experience from a diverse background of the most sophisticated engines.
Wiseco's Pro Tru line creates the best value in forged pistons today.
These American made pistons are forged and machined by skilled Ohio
craftsmen with state-of-the-art forging presses and CNC machines. By
using dedicated forgings specific to the final piston shape, Pro Tru pistons
are stronger and lighter than industry standards.
Pro Tru sets include plasma moly 1/16, 1/16, 3/16 pre-gapped ring
packages which provide excellent seal, friction reduction, and long life. Pro
Tru pistons also come in a variety of volumes that allow the engine builder to
choose the exact compression ratio required for their engine.

1 Dome and reverse dome shapes have smooth contoured surfaces for
better combustion and optimal quench for detonation reduction!
2 Symmetrical valve pocket designs allow maximum flow around the valves
during overlap and accommodate oversize valves and high lift cams.
3 New screen printed skirt coatings for 2010 use Wiseco’s proprietary Armor
Glide™ material. Superior to graphite or Teflon based formulas, benefits
include longer piston life, increased horsepower, noise reduction, and much
tighter dimensional tolerances than typical spray-on coatings. Controlled
curing processes guarantee the best possible results.
4 Complex Piston skirt profiles reduce power robbing friction and rock, which
promotes stability in bore for optimum ring seal.
5 Precision machined ring grooves provide excellent surface finish and flatness for maximum ring seal and minimized blow-by and oil consumption.
6 World class, ISO Certified, forging facility that utilizes the latest technologies, featuring complex forged shapes, advanced materials, and featurealigned grain flow technology.

With the leading tip of the lock in
the 12 o'clock position, insert your thumb thru the
center of the lock and hook it under your thumbnail
at the 10 o'clock position (roughly 1/2" to the left
of the leading tip). Install the leading tip into the 11
o'clock position of the groove. (If the wrist pin hole
intersects the oil ring groove, lock installation is
slightly more difficult as the lock will catch on the
bottom ring land).
The leading edge of the lock should catch in the
groove, allowing it to stay on its own. Continue by
applying pressure with a counter-clockwise motion
until it fully snaps into place.
The correct number of Spiro Locks MUST
be installed in each piston or severe engine
damage may occur. Do not over-stretch or reuse Spiro Locks. Do not install Spiro Locks in
press-fit pin applications.

1 Generous Valve Pocket designs that allow maximum flow around valve.
Note: Piston to valve clearance must be checked.
2 Piston Crown shapes designed to promote maximum Intake Charge efficiency thru scavenging mixture “Cross Flow” during intake and exhaust
valve overlap. More fuel and air equals more horsepower!
3 Pistons designed to optimize squish or quench during compression combustion cycle event, resulting in resistance to detonation and pre-ignition.
The end product is longer engine life and increased horsepower potential.
4 Complex Piston skirt profiles that reduce power robbing friction, yet promote
stability in bore for optimum ring seal. Wiseco has added skirt coatings to
the long list of standard features on our stocked Sport Compact pistons!
5 Precision machined ring grooves with proper orifice/accumulator volume
using calculated groove root diameters and axial widths, featuring excellent
surface finish and flatness providing maximum ring seal and minimizes
blow-by and oil consumption.
6 World class forging facility that utilizes the latest technologies featuring
complex forged shapes, advanced materials, and featured-aligned grain
flow technology.

• Pistons listed with a compression ratio range: low number is with un-cut deck, high number is block decked to .030 piston to cylinder head clearance.
• Always check piston to valve clearance - If using VTEC or like mechanisms-check w/ longer duration higher lift lobe.
• Always run at least .030 piston to head clearance including gasket thickness.
• If piston appears to be different than expected, please do not hesitate to call Wiseco at 800-321-1364 to verify compatibility.
1. Most Wiseco pistons have offset pins. Offset same as o.e. for quietest operation (pin offset will be opposite of direction of engine rotation).
2. Due to a compression height that may protrude above the deck, it is recommended that a .040" thick head gasket is used.
3. Uses an extra thick (.200") wall piston pin. Optional .225" wall, tool steel pins also available.

These gaskets use a high pressure steel laminate design. They will withstand
extremely high shear forces that occur between an aluminum head and iron block.
It's internal embossments expand with heat to create a better seal when under
extremely high combustion pressures and temperatures - as is the case with heavy nitrous and turbo-charged applications.

Tapered Ring Compressor Sleeves
• Machined from Wiseco sleeve forgings for the same Wiseco forged piston toughness.
• Hard anodized and Teflon coated for low friction and long wear resistance.
• Sleeves have a smooth radius that tapers down to the specific bore size.
• Compresses the piston rings smoothly and evenly.
• Greatly reduces the difficulty with installing thin high-performance oil rings.

These Brush hones have been specifically designed to
clean the surface of the cylinder bore and provide a fresh
cross-hatched surface without removing material (which
can increase piston to wall clearance and ring end gap).
Always use an ample amount of honing oil to carry away
debris. Wash cylinders thoroughly, with hot soapy water,
until paper towels remain clean with no signs of discoloration. Then prep cylinders with any anti-rust agent.

CRANKS & RODS
• 4340 steel forgings.
• Special bushing material for optimum friction
reduction.
• Proprietary bolts produced by ARP to K1 specification with asymmetrical threads to equally
load each thread when under tension.
• Pin oiling.
• Heavy radii.
• Thicker blades.
• Double bridged caps reduce housing bore
distortion.
• No ridge between the blades to act as a stress
riser.
• Rod offset is designed to center small end to
bore center.
• Big end housing bore is held to +/ .000050” (50
millionths).
• Center to center less than .001”.
The relationship between K1 and Wiseco is an
industry first. For the first time, rotating assembly
components are being designed around each other
from their inception. This enhances strength and
eliminates mass.
The professional engine builder will note that the
assembly balances well and fitment is exceptional.
Power and longevity are increased through a reduction in mass, friction, and windage.

You've spent a lot of time and money building an engine...
don't risk damage by failing to take a few minutes to put it together correctly.
It's important to note that a fastener is like a very stiff spring and it must be stretched a
specific amount. The material’s ability to “rebound” like a spring is what provides the
clamping force to keep the rod bolted together. If you do not stretch the bolt enough
there may not be enough clamp load to keep the rod cap in place, which could result
in broken bolts or spun bearings. If you stretch the bolt too much, you can exceed
the yield strength of the fastener which will weaken it and cause it to fail. Either of
these two conditions can result in catastrophic damage to your engine. Always
follow the manufacturer’s instructions to prevent damage to your engine.
Methods used for tightening Rod Bolts
Stretch Method: Measuring bolt stretch is the most accurate method for tightening
rod bolts and insures the correct pre-load. Simply measure the free length of the
bolt before tightening, lube the bolt threads and rod spotface. Install the bolt into the
rod and tighten until the bolt is stretched the proper amount. K1 Technologies offers
an economical bolt stretch gauge for this purpose.
Torque & Angle Method: Do not confuse this with the “Torque to Yield” method. Torque
to Yield stretches the bolt to a point where it will no longer return to the original length when
loosened and requires the bolt to be replaced after each use. When using the Torque & Angle method, you
lube the bolt threads and rod spotface, tighten the bolt to a low torque value (as prescribed on the instruction sheet) then, using an angle gauge, turn the bolt a prescribed number of degrees to properly stretch the
bolt. This method uses the highly accurate pitch of the bolt thread to control the amount of stretch.
Torque Method: Torque does not measure clamp load and only measures the amount of friction that must
be overcome to turn the bolt. The friction of the mating surfaces of the threads, rod spotface and bolt flange
change with each tightening. When you consider the fact that different amounts and types of lubes also
change the friction, using the torque method is like trying to hit a moving target that you cannot see. K1
Technologies does not recommend the use of or provide torque values for tightening bolts.
Setting a torque wrench at a given number and tightening
until this set amount of torque is reached is easy, but it can be
highly inaccurate. A torque wrench only measures the amount
of resistance it takes to turn the bolts. The amount and type
of lube that is used will affect the actual clamp load provided
by the bolts. Also, each time a bolt is tightened, the mating
surfaces of the threads, the spotface on the rod and flange
of the bolt get smoother, which changes the amount of torque
that is required to properly tighten the fastener.

A bolt is simply a very stiff spring and it must be stretched a
predetermined amount to keep the rod cap on and the bearing
from spinning.

CRANKS & RODS
Not only do connecting rod bolts see the same tension loads
that try to pull a connecting rod apart, the total weight of the
tower portion of the rod is trying to follow the piston up through
the cylinder head. Connecting rod bolts are the most highly
stressed fastener in the engine! They need to be properly
tightened.

Boring & Honing Instructions
Adherence to proper boring and honing procedure is essential to overall
ring performance. To ensure that the bore finish will retain an oil film, it is
vital that the guidelines listed below are followed for cast iron bores.
• Install and torque main bearing caps
• Use torque plates. This simulates the distortion that occurs when the
cylinder head is mounted to the block. (hint: After boring and honing, leave
the torque plates in place and fit/gap the piston rings to their respective
cylinders.)

• Allow for a minimum of .003" excess material for use as honing stock.
• Intermediate hone to within .0005" of finished size with #220-#280 grit
stones. (With diamond stones use #280-#400 grit.)
• Finish hone with #400 grit stone or higher. (Use #600 grit diamond stone.
If using hand operated equipment, set drill speed between 200-450 rpm.)
• Finish with an appropriate stone or tool to achieve desired plateau finish
(see below).

Why a Plateau Finish?
Plateau honing is the popular name for the process that replicates the
cylinder bore surface finish normally produced by the rings after they have
worn down the surface peaks during "break in". This technique produces
flat areas or plateaus (Rk) on the cylinder wall after finish honing by using
a very fine grit stone or a PHT type brush tool to remove the peaks (Rpk)
from the surface. This lowers the overall roughness average (Ra) while
maintaining valley depth (Rvk) in the cross-hatch pattern of the cylinder
wall. A high Rvk value is very desirable for oil retention qualities and will
substantially reduce "break in" time and increase ring life.
Example of Plateau Finishing

Finish Size..........................4.030"

First Finish.........................4.0290"................. 30-36
Second Finish...................4.0295"..................20-25
Third Finish.......................4.0300"...................7-14
Ra (Roughness Average) = Used to describe surface roughness as an
average between the peaks and valleys that exist in a finish over a specified
area, usually micro inches.
Rpk (Peaks) = Average peak height.
Rvk (Valleys) = Average valley depth.
Cross Hatch = The pattern of intersecting parallel lines left after finish
honing operations are completed. The smaller the intersecting angle, the
larger the area (Rk) between the hone marks.
Cross Hatch Pattern
Maintaining the proper cross hatch angle is important for two reasons; 1. Oil
retention on the cylinder wall and 2. The rate of ring rotation. Excessively
shallow cross hatch angles can hinder or slow down the necessary ring
rotation that allows dissipation of heat. It can also leave too much oil on the
cylinder wall allowing the rings to skate over the surface leading to excess oil
consumption. Too steep of a cross hatch angle may not provide adequate
oil retention and can result in dry starts and premature ring wear. A steep
pattern angle can also create excessive ring rotation that will accelerate
ring and piston ring groove wear.

Ring Terminology
Axial Clearance: The distance between the ring axial height and the piston
ring groove width.
A. Neutral Barrel: A term used to describe a piston ring that
has no torsional bias or twist.
Axial Height: The width (thickness) of the ring in the axial direction.
B. Positive Twist: An asymmetric change in the ring cross
section that causes it to twist in an upward direction
(toward the piston crown) aiding ring sealing of the top and
bottom of the ring groove. Positive twist is used only on
top compression rings.
Back Clearance: Distance between the inside diameter of the ring and
the back of the ring groove when the ring is flush with the ring land.
D-wall: A specification established by the Society of
Automotive Engineers (S.A.E.) that dictates the radial
width of a standard automotive piston ring by the use of
the following formula: Bore diameter divided by
22 = radial thickness (3.386” divided by 22 = .154”)
.154"➞
➞
End Gap: The end gap clearance when the ring is compressed to the
bore diameter.
Gas Nitrided: A process used to harden the perimeter of a ring where
nitrogen atoms penetrate the base material and form an extremely hard
outer layer that provides excellent wear and scuff resistance.
A
B
C. Reverse Twist: An asymmetric change in the ring cross
section causing the ring to twist downward (toward the
piston skirt) that enhances the second compression ring’s
oil scrapping properties.
C
Radial Width: The width of the ring in the radial direction.
Ring Axial Sides: The top and bottom surfaces of the ring.
Ring Face: The section that contacts the cylinder wall.
Torsional Twist: The installed position of the ring due to a
chamfered area on either ring side that helps the ring cross-seal.
Ring Gaps
As a piston moves down on the power stroke, combustion pressure
accumulates in the land area of the piston (between the top ring and
the 2nd ring.) This accumulation of pressure can cause the top ring to
unseat from its sealing area at the bottom of the ring groove.
This is addressed by increasing the gap area of the 2nd ring. This
affords a controlled release of the inter-land pressure, and keeps the
top ring seated on its lower sealing surface for improved performance.
Ring Gap Table Instructions
1) Cylinder bore size must be in inches. If measuring millimeters, divide
bore by 25.4.
2) Multiply your bore size by the “x Bore” column for your application.
Good
NOTE: The chart above is a general end gaps guideline. Each ring should
be fitted to the particular cylinder in which they are to be installed. The
gap on the 2nd ring should always be larger than the top ring end gap,
this will help
reduce top ring
