1.5 Inch Lift Kit | FOX 2.5 Performance Elite Coil-Over | Chevy Trail Boss or GMC AT4 1500 (19-24) 4WD

Built for Trail Boss and AT4 owners who want stance, performance, and tire clearance without compromise. This 1.5-inch lift kit pairs FOX 2.5 Performance Elite remote-reservoir coil-over shocks up front with heavy-duty tubular upper control arms, plus rear fabricated blocks and complementary FOX 2.0 shocks. You get up to 35" tire clearance (Chevy) or 33" (GMC) while preserving driveline geometry and maintaining the truck's factory handling feel.

Installed and serviced at Road Runner Wheels & Tires. Most kits go in the same day. Call (678) 400-6467 to schedule.

What you get up front

• FOX 2.5 Performance Elite Coil-Over Shocks — Remote reservoir design with DSC adjusters (10 low-speed and 12 high-speed compression settings) keeps fluid temps down during aggressive driving. Built-in caster correction for confident highway manners and trail performance.
• Heavy-Duty Tubular Upper Control Arms — 1.5" OD x .120-wall construction with indexed ball joint cups for proper geometry and additional down-travel. Greaseable ball joints and maintenance-free frame bushings mean years of quiet, durable operation.

Out back

Fabricated steel lift blocks with longer u-bolts keep the rear proportional and stable. A matching set of FOX 2.0 Performance shocks round out the package, tuned to work in concert with the front end for balanced ride quality on pavement and off-road terrain.

Pick your shocks

• FOX 2.0 Performance Series — A capable step-up from stock with a solid balance of daily comfort and light-to-moderate trail duty.
• FOX 2.5 Performance Elite — Top-tier remote-reservoir design with DSC adjusters, race-proven internals, and maximum adjustability for those who demand the smoothest, most capable ride both on and off pavement.

Important notes

• Max tire clearance is 35" on Chevy Trail Boss or 33" on GMC AT4 — verify your chosen tire size against these limits.
• Kit is engineered for 4WD models (19–24) only; not compatible with 2WD variants.
• Factory driveshaft geometry is preserved, but confirm current suspension state with our team before ordering.
