Product Details

This high-quality 3.5" HD Suspension Lift Kit is designed for 2020-24 Chevrolet Silverado 2500HD and GMC Sierra 2500HD 2WD/4WD models, delivering increased ride height for enthusiasts looking to run up to 35" tall tires with enhanced off-road performance. The system levels the vehicle from front to rear, creating a more aggressive and commanding stance while maintaining excellent drivability.

The factory GM upper control arms are replaced with Fabtech heavy-duty tubular ball joint upper control arms, engineered for strength and durability. 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 both on-road and off-road use.

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 and working in conjunction with the upgraded upper control arms to maintain proper suspension geometry.

This premium suspension system is equipped with Fabtech Dirt Logic 2.25 shocks, constructed with stainless steel bodies and NitroSteel® piston rods for maximum corrosion resistance and durability. The front shocks feature remote aluminum reservoirs that help reduce heat buildup and provide consistent damping performance in rugged terrain. These Dirt Logic shocks deliver superior ride quality on the highway with exceptional off-road damping control.

This 3.5" HD lift kit is built with high-quality components that enhance strength, reliability, and performance while giving the truck a bold and confident presence.

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
