Product Description

The factory rubber-bushed control arms on a G-body flex under hard acceleration and don't give you any way to correct pinion angle or rear-end alignment. This kit replaces both the upper and lower arms with tubular, TIG-welded pieces that use polyurethane greasable bushings, adding real strength while giving you the adjustability to dial in your setup properly.

The upper "Ultimate Arms" adjust on-car, so you don't have to pull the arm to make changes, and the self-lubricating race rod end keeps things smooth without constant maintenance. It's a direct bolt-in replacement using factory hardware, making it a straightforward upgrade for anyone serious about improving traction and rear suspension geometry on their G-body.
