TIMBREN SES Suspension Upgrade, Rear Kit (2005-2023 Chevrolet Silverado & GMC Sierra 2500 HD)

This SES Suspension Upgrade fits the rear suspension of Chevrolet Silverado 2500/3500 & GMC Sierra 2500/3500 trucks. We've engineered our hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down on the rubber springs the harder they work to prevent rear end sag. Whether you're pulling a trailer or carrying a heavy load in the bed of your truck, our hollow rubber springs adjust automatically to keep your GM 2500 or 3500 truck level at all times.

This SES Suspension Upgrade replaces the bumpstops on the frame. Its unique design ensures superb ride quality - loaded or unloaded. (There should be a 1/2" to 1/2" gap between the rubber spring and axle to ensure unloaded ride quality.) Unlike other auxiliary spring systems, the SES Suspension Upgrade guarantees the best of both worlds.

GMRCK25D replaces the bumpstops on the rear suspension of the 2011-Present GMC Sierra and Chevy Silverado 2500HD and 3500HD pickup truck models.

This kit is rated at 8600 lbs capacity. Even though you're increasing the spring rate by adding this upgrade, this does not increase the GVWR (Gross Vehicle Weight Rating) of your GM 2500 or 3500 truck. Please make sure that the load does not exceed the GVWR set by the manufacturer.

More Safety
When extra weight makes your 2011 to present Chevy and GM 2500 and 3500 trucks squat in the back, the front end lifts up reducing traction on the front tires. Not only that, if the front is too high your headlights will shine into the eyes of oncoming traffic instead of pointing down on the road ahead.

Timbren SES upgrades are designed to keep your vehicle level at all times. This will increase traction on the front tires, improve overall steering and keep your headlights pointing down on the road where they belong.

More Stability
If extra weight makes your GM truck top-heavy, you’re going to experience body roll and sway. There’s nothing more challenging than trying to keep your vehicle moving on a straight path when the load is unstable.

Timbren SES upgrades offer you more stability and peace of mind by eliminating suspension sag and reducing body roll & sway.

More Comfort
Too much weight can cause your 2500 or 3500 HD truck to bottom out if you're driving over bumpy and rough roads. All this road shock will compromise an otherwise comfortable ride.

Improve your ride quality by installing Timbren SES upgrades on your Silverado or Sierra 2500 or 3500 trucks, guaranteed to provide a softer, smoother ride ... empty or loaded.
