Improve load support, handling, and ride stability with the Timbren GMRCK35S Suspension Enhancement System. Designed for the rear suspension of select Chevrolet Silverado 3500 HD and GMC Sierra 3500 HD models, this kit helps reduce vehicle squatting, sagging, sway, and suspension settling when hauling or towing. Its 8,600-pound weight capacity provides dependable support for demanding truck applications.
Timbren SES Kits use durable rubber springs that absorb road shocks and automatically adjust to changing loads and road conditions. Unlike air-assisted suspension systems, the GMRCK35S does not use airlines, fittings, compressors, or other components that can leak or require regular maintenance. The progressive spring design provides additional support under load while preserving a comfortable ride during everyday driving.
Installation is straightforward and requires no drilling, airline routing, or specialized equipment. The kit bolts into place using basic hand tools, allowing installation in minutes on compatible applications. Once installed, the maintenance-free rubber springs provide long-term suspension enhancement backed by Timbren’s lifetime warranty. This rear kit is a practical solution for drivers who need improved control and stability without the complexity of an air suspension system.
The Timbren GMRCK35S is compatible with select 2009 and 2010 Chevrolet Silverado 3500 HD and GMC Sierra 3500 HD applications. Verify vehicle year, model, suspension configuration, and fitment before ordering.
