Timbren GMRCK25 SES Rear Suspension Enhancement System for 1988-2000 Chevrolet & GMC K1500/K2500
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1988-2000 Chevrolet and GMC K1500, K2500, and Suburban models.
The Timbren SES (Suspension Enhancement System) GMRCK25 is engineered to eliminate vehicle squat and sagging under heavy loads. By replacing the factory bump stops with high-performance Aeon hollow rubber springs, this kit provides a progressive spring rate that automatically adjusts to keep your truck level and stable. This significantly reduces trailer sway and improves steering control without the complexity of traditional air bags.
Installation is a direct bolt-on process that requires no drilling or airline routing. These rubber cushions absorb road shocks and improve ride quality while preventing the suspension from bottoming out. Designed as a "fit it and forget it" solution, the system requires zero maintenance and features no fittings or lines to leak.
