3.5" 2007-2013 GMC Sierra 1500 4WD Knuckle Lift Kit by Rough Country

The Rough Country 11930 3.5" Knuckle Lift Kit is the perfect suspension upgrade for your 2007–2013 GMC Sierra 1500 4WD, delivering an aggressive stance, increased ground clearance, and excellent everyday drivability. Designed to strike the ideal balance between appearance and performance, this all-inclusive kit provides the lift you want without going overboard.

At the center of this system are precision-engineered lifted knuckles that retain your factory suspension components for dependable operation and simplified installation. Unlike basic spacer kits, the lifted knuckle design helps reposition the CV axle for improved clearance from the lower control arm, reducing CV boot stress and extending drivetrain component life.

Front strut spacers or new struts (see options) work with the knuckle system to achieve the proper ride height while maintaining factory geometry. A supplied differential drop spacer system and differential skid plate help preserve driveline angles and protect underbody components when tackling rough terrain.

In the rear, heavy-duty 3" fabricated lift blocks and extended U-bolts provide dependable strength and longer service life compared to cast alternatives. This setup levels the truck front to rear, eliminating the factory rake for a clean, aggressive stance.

This kit includes (2) Premium shock absorbers and is compatible with Rough Country’s full lineup of upgraded shock and strut options, including N3, V2, M1, and premium Vertex reservoir shocks.

Backed by Rough Country’s Limited Lifetime Replacement Warranty, this lift kit is built for lasting performance on-road and off-road.
