Enhance your Chevrolet Trail Boss or GMC AT4 with a robust 4 inch lift.
The Fabtech Motorsports Lift Kit Suspension is engineered specifically for the Chevrolet Trail Boss and GMC AT4, providing a substantial 4 inch lift on top of the factory 2 inch lift. This system allows for the installation of 35 inch tall tires, elevating the vehicle's stance to match that of a 1500 with a 6 inch suspension. The design ensures excellent drivability both on and off-road, with zero bump steer throughout the suspension cycle, which minimizes driver fatigue and enhances overall vehicle performance.
This lift kit features heavy-duty components, including 1/4 inch thick steel crossmembers and extended length ductile iron steering knuckles, which contribute to the system's strength and stability. The factory coilover shocks are retained and relocated to maintain stock ride quality while achieving the desired lift. Additionally, the kit includes oversized tie rods designed to accommodate larger tires, ensuring durability and reliability under various driving conditions.
The rear lift is achieved by replacing the factory 2 inch block with a 5 inch block and u-bolt system, allowing for additional lift without compromising load carrying capacity. The heavy-duty front differential skid plate protects critical components from off-road obstacles, while the extended length monotube shocks provide corrosion resistance and durability. This comprehensive lift kit is designed to enhance the performance and appearance of your vehicle, making it a valuable addition for off-road enthusiasts.
