Upgrade your vehicle’s rear suspension with the Timbren GMRYS4 Suspension Enhancement System (SES Kit). Designed for select Cadillac Escalade RWD and Chevrolet Avalanche applications, this rear suspension kit provides a 6,000-pound load capacity to help reduce squatting, sagging, suspension settling, and trailer sway. Timbren’s rubber spring technology automatically adjusts to changing loads and road conditions while cushioning shocks for improved handling, stability, and control.
The Timbren GMRYS4 uses durable rubber suspension components instead of airbags, airlines, compressors, or fittings, eliminating common sources of leaks and ongoing maintenance. The kit is engineered for a straightforward installation with no drilling or airline routing required, allowing installation with basic hand tools in a matter of minutes. Once installed, the system is designed to deliver dependable, trouble-free performance for the life of the vehicle.
Timbren has been a leader in rubber spring technology since 1965, and the GMRYS4 reflects that experience with a reliable suspension solution for demanding towing and hauling conditions. The rear SES Kit helps maintain a more controlled ride under load while supporting enhanced safety and driver confidence. Built for long-term use, this Timbren suspension enhancement system is backed by a lifetime warranty and is an effective upgrade for vehicles that need additional rear suspension support.
