INTAKE VALVE
KAT-A3359-R02 Intake Valve - Hollow Stem (2.100" X 8mm Shaft)
These industry exclusive light weight hollow stem valves weigh only 83 grams and are the closest thing to
running titanium valves for a fraction of the price. Manufactured using demanding tolerances, it weighs only
10 grams more than a standard 2.00” hollow stem valve and 30 grams less than similar sized solid stainless
valves. In testing compared to a standard 2.080” Stainless Steel valve, our hollow valve allowed the
valvetrain to rev 1000 RPM higher before any signs of instability occurred.

end. Assembled with Katech forged LS7 pistons 4472A, 4472B or 4498A. With customer
supplied rods only.
PSI-LS1511 Valvespring - Beehive single spring - high lift
Katech’s Cell 1 Valvetrain Test System is always working on valvetrain
stability and durability for racing and street performance packages. Beehive
springs are consistently more stable because of reduced natural frequencies
and lower mass at the top of the spring. This spring is the best all around
because it is stable, controls valves on the most radical cams, and allows more
lift than almost any available.

THROTTLE BODY
FRONT DRIVE
Our throttle bodies have the highest level of detail in the
industry. The body is CNC machined for accurate reproduction
of our extensively developed porting. The butterfly is bullnosed
on the CNC on both leading and trailing edge and the shaft is
milled to increase cross-sectional area of the throttle body. All
