Description
If you’re running a 3/4 or 1-ton GM truck, suspension sag under load directly impacts handling, braking performance, and tire wear. The Timbren SES Kit restores your truck’s original ride height and load-carrying capacity without the harsh ride quality of traditional coil springs, giving you predictable performance whether you’re towing, hauling, or daily driving.
This bolt-on rubber spring system uses elastomer technology to provide progressive support that increases with load—meaning your truck stays level when it matters most. Installation is straightforward with all hardware included, making this an ideal upgrade for anyone looking to improve truck dynamics without a full suspension rebuild.
