Product Details

This high-quality 3.5" HD suspension lift kit is engineered for 2020-24 Chevrolet Silverado 3500HD and GMC Sierra 3500HD 4WD models, delivering increased ride height for enthusiasts looking to run 35" tall tires with enhanced off-road capability. The system levels the vehicle front to rear, giving it a more aggressive stance while maintaining confident on-road manners.

The factory upper control arms are replaced with Fabtech heavy-duty tubular ball joint upper control arms designed for strength, durability, and proper suspension geometry. These arms are constructed from 1.50" OD DOM steel tubing and feature oversized high-travel ball joints that are significantly larger than stock, providing increased strength and reliability for demanding on-road and off-road conditions.

Fabtech precisely sets the ball joint angle to allow full suspension travel without binding throughout the entire range of motion. Forged torsion bar keys replace the factory units, allowing additional ride height adjustment while working in conjunction with the upgraded upper control arms to maintain correct alignment and ride quality.

The rear suspension is leveled using 2" rear lift blocks and U-bolts, helping maintain proper stance without compromising ride quality or load-carrying capacity. The system is completed with Fabtech’s top-of-the-line Dirt Logic 2.25 shocks, constructed with stainless steel bodies and NitroSteel® piston rods for maximum corrosion resistance, durability, and consistent damping.

This 3.5" HD lift kit is built with premium components that enhance strength, reliability, and overall performance while giving the truck a bold, commanding presence both on and off the road.

The legendary Dirt Logic 2.25 rear shocks are constructed of a stainless steel body with NitroSteel(R) piston rod for maximum corrosion resistance and durability. Superior ride quality both on and offroad. Excellent dam
