Enhance the load-handling capability and stability of your truck with the Timbren timGMRTT35D Suspension Enhancement System. Designed for the rear suspension of select 2011 Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500 HD, GMC Sierra 2500 HD, and GMC Sierra 3500 HD applications, this Severe Service kit is engineered for slide-in campers, salt spreaders, and other demanding hauling conditions. With an 8,000-pound weight capacity, it helps reduce suspension sagging, improve handling, and provide added confidence when carrying heavy loads.
Timbren SES Kits use durable rubber suspension springs that absorb road shocks and automatically adjust to changing loads and road conditions. The progressive spring design supports the vehicle under load while helping maintain a smoother, more controlled ride. Unlike air suspension systems, the Timbren system has no airlines, compressors, fittings, or controls that can leak or require regular adjustment, making it a dependable solution for work trucks and heavy-duty applications.
Installation is straightforward and requires no drilling, cutting, or air lines. The kit bolts into place using basic hand tools, allowing you to upgrade the suspension in a matter of minutes. Built on Timbren's experience in rubber spring technology since 1965, the timGMRTT35D is designed for long-term service and backed by a lifetime warranty. Verify vehicle configuration and application details before installation to ensure proper fitment.
