Upgrade the rear suspension of your 2019–2020 Chevrolet Silverado 1500 with the Timbren GMRSTT15 Suspension Enhancement System. Designed for severe-service applications such as slide-in campers and salt spreaders, this rear kit helps reduce vehicle squatting, sagging, suspension settling, and trailer sway. Timbren’s rubber spring technology provides additional support under load while helping maintain a more controlled and stable ride.
Timbren SES Kits use durable rubber cushions that absorb road shocks and automatically respond to changing loads and road conditions. Unlike air suspension systems, the GMRSTT15 has no airlines, fittings, compressors, or valves that can leak or require adjustment. The maintenance-free design delivers dependable suspension support without the need for periodic air pressure checks or servicing.
Installation is straightforward and requires no drilling, cutting, or airline routing. The kit bolts into place using basic hand tools, allowing installation in minutes on compatible applications. Once installed, the rubber springs provide progressive load support while preserving the vehicle’s unloaded ride quality as much as possible. This design is well suited for drivers who regularly carry heavy equipment or operate a slide-in camper or salt spreader.
As a leader in rubber spring technology since 1965, Timbren backs the GMRSTT15 with a lifetime warranty. The kit is engineered to improve handling, cushion road impacts, and provide added confidence when hauling or towing. Confirm vehicle configuration and application details before installation to ensure proper fitment for your Chevrolet Silverado 1500.
