Profit From the Growing Market
in Aligning Lowered and Altered
Ride Height Vehicles
Take Advantage of the Profitable Market in
Aligning Altered Ride Height Vehicles
The number of altered ride height vehicles is growing
rapidly and presents a very profitable market for shops
capable of servicing these specialized vehicles. Hunter
WinAlign Tuner™ software, hardware and procedures
enable your shop to align altered ride height or “tuner”
vehicles and increase your shop’s profitability.
When modifying the
height of a vehicle,
the effect on the
vehicle’s toe can
be dramatic.
Modifying a vehicle’s ride height may cause changes in
alignment geometry that result in improper camber, caster
and toe. Changes in tire and wheel offset can have drastic
effects on the scrub radius. WinAlign Tuner software
instructs your technicians on how to adjust for these
factors and provide the best possible solutions for vehicle
handling and tire life.
Vehicle modifications, such as altering ride height, can
negatively affect vehicle performance in several ways
including:
• Accelerated tire wear
• Bump steer
• Improper handling
• Accelerated suspension component wear
The effect
lowering
a vehicle
has
on camber
A vehicle lowered by 1” may experience a camber change
of approximately -.8˚or more, whereas a vehicle lowered by
3” may experience approximately a -3.8˚ camber change or
more.

WinAlign
Tuner
Software
Shows Your Technicians How to Detect
“Bump Steer”
One of the most common results of lowering the height
of a vehicle is bump steer. This is the result of a lack
of parallelism in the steering linkage. Correcting this
phenomenon presents additional profit opportunities for
your shop by installing bump steer kits, special steering
arms and rack repositioning kits.
Hunter WinAlign Tuner Software Helps
You Take Advantage of Additional Profit
Opportunities
Many modified vehicles require the use of special kits or
parts to return them to an alignable condition. Typical
examples are adjustable control arms or camber plates.
The enhanced Tools and Kits feature of WinAlign Tuner
software displays any special tools or kits that will
be needed for the job. Your shop may also have the
opportunity to sell other parts and components such as
dropped spindles, sport springs and sway bar kits.
Many technicians may not be familiar with the
fundamental procedures for modifying ride height.
WinAlign Tuner software provides guidelines for
modifying the vehicle and altering specifications.
Exclusive Features Allow Alignment of Modified Vehicles
Choose to Maximize Performance or Tire Life
Enhanced Tools and Kits
WinAlign Tuner™ software enables a suggested
set of alignment procedures based on the vehicle
owner’s choice to either maximize performance or
tire life.
Tools and Kits enables the technician to not only view
the parts necessary for modification and alignment,
but also access the parts manufacturers’ websites.
Bump Steer Measurement With Live Ride Height
Camber, toe, total toe and steer ahead are measured
as the vehicle is raised and lowered. The results
are charted on-screen to allow the technician to see
the change in values through a range of heights and
compare values before and after modification.
BEFORE
AFTER
Measurements are captured
automatically as the vehicle
is raised and pulled down,
using the Bump Steer
Measurement and Live Ride
Height kits.
Bump Steer Measurement System
(kit number 20-2011-1) and Live
Ride Height (kit number 20-2050-1)
are optional features of WinAlign
Tuner software.

Live Ride Height Adjustment Feature
H
unter’s Live Ride Height Adjustment feature reduces the
time required to make ride height changes on the vehicle.
The technician simply installs the ride height targets onto the
fenders and measurements are instantly transmitted to the
console. Ride height changes are tracked continuously.
Live Ride
Height Targets
allow ride
height to be
taken around
the vehicle
quickly and
easily.
n H
unter Live Ride Height Adjustment feature allows
the technician to easily measure, adjust, jounce and
confirm ride height.
Ride height can change over time
as a vehicle ages. These changes
in ride height can prevent proper
alignment.
n Accurately measure and adjust ride height in just one trip around the vehicle.
Live Ride Height Measurement Kit 20-2050-1
n Integrate with WinAlign Tuner™ software to better service modified vehicles.
n Make ride height measurements and adjustments in half the time.
Includes four targets used for measuring ride height. Kit 20-2050-1
requires a WA or 811 Series console running WinAlign® software
version 10.0 or greater and HawkEye™ HS401 or DSP600 sensors.
n U
se the Suspension Body Dimension Audit feature to
determine alignability or need for collision repairs.
A Perfect Tool for WinAlign Tuner™ Software
Use Live Ride Height to validate
lowering kit results.
Accurately position the ride
height of the vehicle for
performance alignment settings.
Easily make staggered ride
height adjustments.
Enhances the Capabilities of the Patented Suspension Body Dimension Audit Feature
The Live Ride Height targets “tell”
WinAlign software where the body is...
The digital camera sensor
targets “tell” WinAlign software
where the wheels are...
And... these same measurements
will tell the mechanical shop if
collision repair is needed.

Rolling Force Lever
Curb-to-Curb Distance
As the Rolling Force lever gets longer, it becomes
easier for road forces to disturb and sometimes steer
the wheels. Because of this, additonal road shock can
be transmitted to the steering wheel. If the Rolling
Force Levers are unequal side to side, the vehicle may
pull. Road force and rolling resistance will act on the
longer lever and try to steer the vehicle away from
straight-ahead.
Curb-to-Curb Distance is the minimum diameter
distance, as measured from the outside of the tire,
needed to turn a vehicle 180°. This measurement
is determined by the wheelbase, tire width and the
vehicle’s maximum turning angle. Loose or damaged
parts, incorrect total toe or modifications to the
wheelbase can affect the turning diameter. The larger
the Curb-to-Curb Distance, the more room a vehicle
needs to turn around.
Tire Temperature Measurements
After a Road Test
Since tire temperature is used to properly build a
custom specification for an altered vehicle, WinAlign
Tuner™ software provides
integrated support for
collecting tire temperatures
using a pyrometer. WinAlign
Tuner software instructs
the technician how to take
temperature readings and
use this information to
establish alignment settings.

Body Roll Angle
Body Overhang
Body Roll Angle is the vehicle body tilt from side to side
that occurs when the wheels are turned from straight
ahead to left/right lock. When the vehicle is steered
from side to side, the body of the vehicle rolls due to a
height change induced by the steering axis inclination
and caster. Excessive cross caster or steering axis
inclination, sagged or broken springs, or broken sway
bar links can contribute to excessive differences in Body
Roll Angles. Minimizing Body Roll Angle will help the
vehicle maintain better traction in turns.
Body Overhang is the distance, either positive or
negative, that the wheel well overhangs the tire. The
measurement should be similar on either side of the
axle. Collisons or body repair may cause differences
in measurement. Wheels with greater offset or width
can produce a negative Body Overhang, which means
that a collision may occur between tire and wheel
well when the springs are compressed.
Body Centerline Offset
Vehicle Modification Guidelines
Body Centerline Offset is the lateral distance between
body centerline and chassis centerline at the front or
rear axle. Both Body Centerline and Body Centerline
Offset may be useful tools when diagnosing the cause
of an excessive thrust angle. Collisions or body repair
may cause these lines to be divergent. Any front-torear difference in body centerline offset will produce
a non-zero Body Centerline measurement, which will
cause dog-tracking.
WinAlign Tuner™ software presents the technician with
information that provides guidelines for altering specs
for modified vehicles.
Enhanced Printouts
Enhanced printouts include bump steer charts for each front
wheel, tire temperature and alignment readings for each tire, and
illustrations of body roll and body overhang measurements.
Bump Steer Winch and Laser Scale
Hunter’s optional Bump Steer Winch and Laser Scale
enables the technician to detect bump steer while
safely pulling down the vehicle at varying increments
to record height change measurements.
Electronic Vehicle Ride Height
Measurement
This WinAlign Tuner™ software procedure measures
and saves the changes in vehicle
height after lowering or raising the
vehicle to view cross ride height.
