Anyone looking for traction? Have you ever heard the term instant center or antiquat?

Don't forget to preorder your custom parts before the G Body Classic on July 12th.

7 HOLE-G SOUTHSIDE MACHINE PERFORMANCE UPPER RELOCATION BRACKETS G-BODY.


TRACTION IS ABOUT GETTING YOUR REAR ARMS AT THE PROPER ANGLE

The term is instant center and the web is full of places to calculate your needs.

The G Body Platform cars react REALLY well to the upper arm being close to level and the lower arms about 4"-5" below the housing.

If you call, we can plot and calculate your current setup and what needs to be done to correct it.

This will allow you to get the upper arms at the proper angle for traction. This will also require a shorter upper arm. You can build a new shorter arm or we can build them for you.

This kit will include brackets for each side, hardware and the spacer needed. Welding required by the installer.
