Enhance offroad performance with a 4 inch lift and superior handling.
Fabtech's suspension lift kit for the Trail Boss and AT4 is engineered to improve both on-road and off-road driving capabilities. This system features a 4 inch lift in both the front and rear, ensuring a balanced elevation that maintains the vehicle's near stock track width for a clean aesthetic. The design incorporates heavy-duty components, including 1/4 inch thick steel crossmembers and extended length ductile iron steering knuckles, which eliminate bump steer and enhance maneuverability in tight spaces.
The kit includes essential components such as rear performance shock absorbers, front steering knuckles, and a heavy-duty front differential skid plate, all contributing to a robust suspension system. The welded box design of the crossmembers adds strength, while oversized tie rods are included to accommodate larger tires. Factory coilovers are relocated using heavy-duty mounts, preserving the stock ride quality while providing the necessary lift.
Additional features include billet spacers that control suspension travel and 5 inch tall steel rear lift blocks that enhance lift without compromising load capacity. The extended length twin tube shocks are designed to deliver a comfortable highway ride while being capable of handling off-road conditions. This comprehensive lift kit is designed for those seeking to enhance their vehicle's performance and appearance.
