Timbren SES Rear Suspension Enhancement System for 2011-2023 GMC/Chevrolet 2500/3500 (GMRCK25DM1)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2011-2023 Chevrolet Silverado and GMC Sierra 2500/3500 trucks.
The Timbren SES (Suspension Enhancement System) GMRCK25DM1 is engineered to eliminate rear-end sag, reduce body roll, and improve overall vehicle stability when towing heavy trailers or hauling maximum bed loads. These hollow rubber springs provide a progressive spring rate, meaning the more weight that is applied, the harder they work to keep the vehicle level. Unlike air bag systems, this setup requires no air lines, no compressors, and no manual pressure monitoring, making it a reliable, maintenance-free solution for heavy-duty work.
This kit replaces the factory bump stops, bolting directly to the frame. When the vehicle is unloaded, the Aeon springs do not contact the axle, preserving factory ride quality; once a load is added, they engage to provide immediate support and prevent bottoming out.
- Eliminates suspension sag and improves headlight aim while towing
- Reduces trailer sway and body roll for safer highway handling
- Simple bolt-on installation into factory mounting points; no drilling required
- Maintenance-free hollow rubber spring construction
- Manufacturer Part Number: GMRCK25DM1
Includes two Aeon hollow rubber springs, vehicle-specific laser-cut mounting brackets, and all necessary Grade 8 installation hardware.
