The stage 1 rear kit is both an economical and easy way to lower the rear of your 63-72 C10′s trailing arm suspension. The air spring and mounting plates replace the factory steel coil spring, allowing a better ride quality and adjustability! Our Stage 1 shock relocator brackets improve shock function by decreasing the shock angle!

The Porterbuilt Bolt-on Body Drop for the 1967-1972 C10 is for those guys who just can’t be low enough! It is designed to make it easier to set the pinch weld level to the bottom of the frame.

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!

The Porterbuilt Stage 2 Rear “Deluxe” Kit for 63-72 C10 is an engineered bolt-in suspension system designed to lower your truck as low as possible while maintaining the factory bed floor. The Stage 2 “Deluxe” is just that, it replaces all the factory crossmembers (from the trailing arm cross-member back) with tubular versions that are designed to bolt right in! It also includes our fully adjustable trac bar for improved handling and performance. If you are looking for the best possible kit to lower your C10 and keep the bed-floor in tact… this is the one!
