The Timbren GMRSTT15 Suspension Enhancement System is designed to add extra rear suspension stability for 2019-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks with the new body style. This heavy-duty setup is built for applications carrying higher center-of-gravity loads such as truck campers, service bodies, or salt spreaders. Using Timbren’s patented Aeon® hollow rubber springs, the system provides progressive load support that activates when additional weight is added, helping control rear-end squat, sway, and body roll. The design maintains a comfortable ride when the truck is unloaded while delivering improved stability under load. Installation is straightforward with a bolt-on design, and the system requires no maintenance once installed. Timbren backs the kit with a lifetime warranty.
