The Timbren GMFK25D Suspension Enhancement System is designed to provide additional front suspension support for 2011-2026 Chevrolet Silverado and GMC Sierra heavy-duty trucks. Using Timbren’s patented Aeon® hollow rubber springs, this front kit helps manage front-end sag and reduces sway when the truck is carrying heavy equipment such as plows, winches, or other front-mounted accessories. The progressive rubber springs activate only when needed, allowing the vehicle to maintain a stable and comfortable ride whether under load or driving unloaded. With a simple bolt-on installation and no required maintenance after installation, this system offers a durable and dependable upgrade backed by Timbren’s lifetime warranty.
