Hotchkis Sport Suspension has developed a Thrust Alignment Kit (http://www.hotchkis.net/mopar_thrust_angle_shims.html) for use with our leaf spring kits, or factory springs and hangers. The process is very simple and involves inserting the necessary shims between the leaf hanger and the body. The kit consists of six (1/32") shims and allows for proper thrust alignment of the rear end.

Additional Information:

Q. What is rear thrust angle and how can I correct it?
A. Thrust angle is the angular difference between 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 zero thrust angle. The presence of a thrust angle can cause the vehicle to "dog leg" or track to the left or right during straight-line driving along with steering & tire wear issues.

Q. Why is thrust angle important?
A. When performing a 4-wheel alignment to your G-Machine, it is imperative that the "Thrust Angle" is adjusted correctly. Having excessive thrust angle in your alignment can cause adverse effects on performance handling. Straight-line stability and steering control can be reduced. Along with an increase in "feathering" tire wear on all 4 tires. The Hotchkis Thrust Shim Kit will allow your alignment shop to properly adjust the thrust for you're A, B, or E-Body Mopar!

How could one accurately measure this angle? What are the thicknesses of the shims in this kit?

Any alignment shop worth a salt can do it with great accuracy. Simple garage method is to check the axle location against a known good reference point further forward in the body.

According to Hotchkis, shims are 1/32 each.
