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 drivers looking to run up to 35" tall tires with enhanced off-road capability. The system levels the vehicle from front to rear, creating a more aggressive and commanding stance.

The factory upper control arms are replaced with Fabtech heavy-duty tubular ball joint upper control arms engineered for strength and long-term reliability. These arms are constructed from 1.50" OD DOM steel tubing and feature oversized high-travel ball joints that are significantly larger than stock, delivering increased durability 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 while working in conjunction with the upgraded upper control arms to maintain proper suspension geometry.

This suspension system is equipped with Fabtech Stealth shocks, featuring a sealed monotube design with a Nitrocarb piston rod for corrosion resistance and protection against rock chipping. These shocks provide a smooth highway ride with reliable damping performance for off-road conditions.

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

This new 4 System capitalizes on Toyota Tundras large wheelwell opening to allow use of 35 tall tires with minimum lift height. The design of this 4 System is a new style of suspension that delivers improved performance
