Lower your 1973-1987 GM pickup while dramatically improving its handling and ride quality. Nicknamed the “square body,” these pickups really benefit from our StreetGRIP suspension system. The complete kit includes special composite leaf springs that shed a considerable amount of un-sprung weight. The trick leaf springs also create a great stance in conjunction with custom coil springs and dropped spindles. Self-lubricating Delrin bushings reduce deflection without making noise. The icing on the cake is a set of Ridetech HQ Series adjustable mono tube shock absorbers. Our shocks are vastly superior to the cheap twin-tube shocks sold in other kits with respect to handling, ride, and durability. When choosing a suspension kit, it’s important to keep in mind that shocks are one of the most important parts of the equation. Ridetech shocks are so good, they carry a million and one mile warranty. StreetGRIP and Square bodies go great together. The proof is in the drive.
