INSTRUCTION MANUAL BEFORE
1. Measure Alignment
The vehicle will need to be measured to determine whether or not the thrust angle requires
adjustment. It is best to have t hi s performed by a 4-wheel wheel alignment professional.
Thrust angle is a common measurement observed i n m ost alignment shops. If your vehicle
requires thrust adjustment, t hen please proceed to the following steps using the Hotc hki s
Thrust Shim Kit.
Terms:
Geometric Centerline: When observing the vehicle in plan view, this is an ima ginary line that
runs through the center of the front wheels and rear wheels
Thrust Direction: When observing the vehicle in plan view, the thrust direction follows an
imaginary line that runs throug h the center of the rear wheels and points in
the direction the rear wheels propel the vehicle. In live axle vehicles, thrust
is typically parallel with the direction of the rear wheels.
Thrust Angle: The angular difference b etween the Geometric Centerline and the Thrust
Direction. The thrust angle is positive when it points to the right and negative
when pointed to the left. The goal is to have this angle to be zero.
2. Raise the Vehicle
Raise the vehicle and safely secure it o n jack stands. Make sure to support the rear of the
vehicle on the chassis rather than the differential.
3. Support the Differen t i al
Place a jack underneath the rear differential pumpkin and apply jacking forc e until the weight
of the differential is relieved. This will allow you to disconnect the front leaf spring mount
without fighting any unwant ed preloads.
4. Install the Shims
Begin unbolting the 4 nuts that secure the front leaf spring mount to the chassis on the side
that requires shimming. Once mount i s so m ew hat detached from the chassis, you can slide in
the amount of shims you require. T he kit comes with 6 shims @ 1/32” thickness.
5. Reinstall Leaf Spring Mount
Reinstall the leaf spring mount in the same manner as removal.

6. Recheck Thrust Angle
Lower the vehicle back to ride heig ht and recheck the thrust angle. Repeat this proc ess of
adding or removing shims until you have zero thrust ang l e.
