Improve load support, ride control, and towing stability with the Timbren GMRG25C Suspension Enhancement System. Designed for the rear suspension of select Chevrolet Avalanche 1500, Chevrolet Tahoe, GMC Savana 2500, Chevrolet Express 2500, and Cadillac Escalade AWD applications, this kit replaces conventional helper springs with durable rubber suspension cushions. Timbren has led rubber spring technology since 1965, providing dependable suspension support without the complexity of air-based systems.
The progressive rubber springs automatically adjust to changing loads and road conditions, helping reduce vehicle squatting, sagging, suspension settling, and trailer sway. They also cushion road shocks and improve handling for a more controlled driving experience when towing, hauling, or carrying uneven loads. With a weight capacity of 6,000 pounds, the Timbren GMRG25C is engineered to add stability and support while preserving a practical, maintenance-free design.
Installation is straightforward and requires no drilling, airlines, compressors, or fittings. The bolt-on design can be installed using basic hand tools, making it a convenient suspension upgrade for trucks and SUVs. Once installed, the system requires no routine air-pressure adjustments or leak checks. Backed by Timbren's lifetime warranty, this rear Suspension Enhancement System delivers long-term support and peace of mind for demanding automotive and towing applications.
