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, providing increased ride height for enthusiasts looking to run up to 35" tall tires with enhanced off-road capability. The system levels the vehicle front to rear, giving it a more aggressive and commanding stance.

The factory upper control arms are replaced with Fabtech Uniball Upper Control Arms that deliver additional wheel travel and increased caster compared to stock components. This added caster improves alignment capability and steering feel, especially when running oversized tires.

Fabtech Uniball control arms are constructed from premium .120" wall, 1.50" OD 4130 chromoly tubing and utilize 1" FK stainless PTFE-lined Uniball bearings in place of traditional ball joints. This heavy-duty design increases strength, durability, and longevity in harsh off-road environments while maintaining a more confident and positive on-road driving feel.

Forged torsion bar keys replace the factory units to allow additional ride height adjustment, working together with the upgraded upper control arms. The suspension is equipped with Fabtech Stealth shocks, featuring a sealed monotube design with a Nitrocarb piston rod for improved corrosion resistance and rock-chip durability. These shocks provide excellent highway comfort with reliable off-road damping.

This 3.5" HD lift kit combines premium components that enhance strength, reliability, and performance while delivering a bold, aggressive appearance. A free 5-year / 60,000-mile powertrain warranty is included for added peace of mind.

Obtain increased wheel travel and mild lift height with this heavy duty Upper Control Arm system. The tubular Upper Control Arms feature 1.25 OD. .120 wall thick chromoly tube construction with 1 diameter Stainless Stee
