This SES Suspension Upgrade fits the front suspension of a Chevrolet Silverado 2500HD/3500HD & GMC Sierra 2500/3500 truck. Our hollow rubber springs are engineered to deliver a progressive spring rate. In other words, the more weight that pushes down on the rubber springs (weight from a snowplow or heavy aftermarket accessories – such as a steel bumper) the harder they work to prevent front-end sag.
GMFK25D replaces the Bumpstops on the front suspension of the 2011-2021 GMC Sierra and Chevy Silverado 2500HD and 3500HD pickup truck and cab and chassis models.
This kit is rated at 8000 lbs capacity. Even though you’re increasing the spring rate by adding this upgrade, this does not increase the GVWR (Gross Vehicle Weight Rating). Please make sure that the load does not exceed the GVWR set by the manufacturer.
