Improved Ground Clearance and Ride Quality: Transform your Sierra or Silverado 2500HD/3500HD with Rough Country's 3.5" Knuckle Lift Kit. Engineered to deliver increased ground clearance, this kit gives your truck the confidence to tackle off-road trails while maintaining smooth, reliable performance on the highway. Choose from Rough Country's premium shock options, N3, M1, V2 monotube shocks, or Vertex reservoir shocks, to match your driving style and maximize ride quality.

Innovative Design and Superior Strength: Built for heavy-duty performance, this lift kit features precision-engineered steel knuckles and forged torsion bar keys for uncompromised durability. Forged upper control arms with OEM-style Clevite bushings maintain factory-like geometry and ensure a full range of motion. Differential drop spacers further optimize driveline angles while reducing CV bind. With clearance to run 33" tires (with proper wheel backspacing), your truck gains both function and aggressive style.

Premium Control Arm Finishes: Customize your build with upper control arms available in a sleek aluminum finish or bold powdercoated red. Both options deliver rugged strength with a premium look to match your truck's style.

Quick and Easy Installation: Designed for a straightforward bolt-on process, this kit requires no cutting, drilling, or welding. With an estimated install time of 4-6 hours and only standard tools needed, you can get your truck lifted and ready to go in a single afternoon.

Backed by a Limited Lifetime Warranty: Drive with peace of mind knowing your Rough Country 3.5" Knuckle Lift Kit is protected by our industry-leading limited lifetime replacement warranty. Built tough and backed strong, this suspension system is made to perform as hard as your truck works.
