Product Description
The Timbren GMRCK25D Rear Suspension Enhancement System (SES) is designed to improve the load-handling capabilities of your 2011–2024 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD trucks. This kit replaces the factory jounce bump stops with progressive-rate Aeon® rubber springs, providing up to 8,600 lbs of additional load support.
Ideal for towing heavy trailers, hauling payloads, or carrying equipment, the GMRCK25D helps eliminate rear-end sag, reduces body roll, and enhances overall stability. The system maintains a comfortable ride when unloaded, thanks to a designed clearance gap between the springs and axle.
Installation is straightforward, requiring no drilling or special tools, and utilizes existing mounting points. The maintenance-free design means no air lines, compressors, or adjustments are needed. Backed by Timbren's Lifetime Warranty and a 100-Day Money Back Guarantee, the GMRCK25D offers a reliable solution for heavy-duty load support.
