Improve load support, handling, and ride stability with the Timbren Suspension Enhancement System, part number timGMRSB4S. Designed for the rear suspension of select Chevrolet Avalanche 2500, Chevrolet Suburban 2500, and GMC Yukon XL 2500 applications, this kit helps reduce vehicle squatting, sagging, sway, and suspension settling when hauling or towing. Its 3,600-pound capacity provides additional support while helping maintain a more controlled and confident ride under changing load conditions.
Timbren SES kits use durable rubber springs that absorb road shocks and automatically adjust to uneven loads and road conditions. Unlike air helper springs, this system requires no airlines, fittings, compressors, or ongoing air-pressure adjustments. The maintenance-free design eliminates common leak concerns and delivers reliable suspension support throughout the life of the vehicle. Built by Timbren, a leader in rubber spring technology since 1965, the kit is engineered for dependable performance in demanding automotive and towing applications.
Installation is straightforward and requires no drilling, air-line routing, or specialized equipment. The bolt-on design can be installed in minutes with basic hand tools, making it a practical upgrade for drivers seeking enhanced rear suspension performance. This rear Suspension Enhancement System also includes Timbren's lifetime warranty for added confidence and long-term value. Verify vehicle application before ordering to ensure proper fitment for your specific model and year.
