Configured with FOX 2.0 Performance Series rear shocks. These shocks feature a 2-inch impact extruded aluminum body, an internal floating piston (IFP) monotube design, a large 5/8-inch hard chrome plated heat-treated alloy steel shaft, a race-developed high-flow piston design, and application-specific valving. Finished in a long-lasting clear anodized finish and backed by a 1-year manufacturer's warranty.
Overview
This 2.5-inch suspension lift kit for the Chevy Trail Boss and GMC AT4 1500 (2025–2026) 4WD Gas models is built around FOX 2.5 Performance Elite coil-over shocks up front, delivering increased travel and the ability to absorb rough terrain while maintaining on-road comfort. The kit provides clearance for up to 35-inch tires and includes all hardware and components necessary for a complete installation.
Up front, the kit uses top-mounted strut spacers, upper control arms, high-arched 1/4-inch thick steel crossmembers, a multipiece differential relocation bracket, and heavy duty skid plates. CNC-machined ductile iron steering knuckles and replacement tie rod ends correct steering geometry at the new ride height while maintaining ESC system compatibility. Sway bar drops, bump stop extensions, brake line brackets, CV spacers, and all required hardware are also included.
In the rear, a heavy duty lift block replaces the factory block to lift and level the stance while retaining ride quality and load capacity. New U-bolts and brake line brackets are also supplied for the rear.
