  1. Porterbuilt 1963-72 Fully Adjustable Trac-bar Kit

    If you are thinking about lowering your C10 truck more than four inches in the rear, a longer trac-bar will be a necessity! The Porterbuilt Fully Adjustable Trac-bar has an overall length of just over 34 inches. The longer the bar, the less side to side shift the differential will experience through suspension travel. The new mounting brackets also relocate the bar lowering the rear roll-center, and the bar length can be tuned while still mounted on the truck!
