Video Tutorial: Fixing Camber Alignment problems on Chevelle, GTO's Old Cutlass, Buick GS, and other A-Bodies
Improve your Handling, Straight Line Stability and Overall Tire Wear with Offset Shafts.
This tutorial explains how the offset shaft installs in the upper control arm and some of the advantages gained by using offset shafts:
Why use offsets?
Whenever we rebuild a stock front end, we recommend installing offset shafts.
Offset upper shafts are used for several reasons:
The Global West Advantage:
- Repair alignment because of frame damage or frame sag.
- Repair alignment due to ride height change.
- Fine tune alignment for racing or performance street applications.
By rotating the offset shaft in the control arm when you install it, you can push the tire towards the fender (positive camber) or in towards the motor (negative camber) to fix the wheel alignment. Another advantage of using the offset shaft is to gain more caster. Caster will help out the front end tremendously.
For most conditions, offset shafts are used for frame issues. They generally give you about 1-1/4 degrees of addition adjustment. However in the performance world, they are perfect for getting the best possible alignment using stock suspension.
One of the keys to better tire life and performance on these older muscle cars is to increase caster and induce some static negative camber. In fact, you want to do this because more caster is going to give the car straight-line stability, a faster steering response and a greater feel. Then, add some negative camber to the mix and your tire life will improve; the offset shaft will allow you to do that.
