Timbren SES Suspension Enhancement System for 2019-2026 Chevrolet Silverado / GMC Sierra 1500 (GMRS15)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2019-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 models (including LTD and Limited variants). This Timbren Suspension Enhancement System (SES) is engineered to eliminate vehicle squat and sagging under heavy loads, providing a level ride and improved handling for towing and hauling.
The system features high-performance progressive-rate rubber springs that absorb road shocks and automatically adjust to uneven loads or road conditions. Unlike air bag systems, these cushions require no air lines, fittings, or ongoing maintenance. The GMRS15 bolts directly to existing factory mounting points using basic hand tools—no drilling or specialized equipment is required for installation.
- Eliminates vehicle squatting and sagging under heavy loads
- Reduces trailer sway and improves overall steering stability
- Maintenance-free design with no air lines or leaks to manage
- Simple bolt-on installation using factory holes (no drilling required)
- Manufacturer Part Number: GMRS15
- Includes a lifetime warranty
