This configuration pairs the FOX 2.5 Factory Series coil-overs up front with FOX 2.5 Performance Elite rear shocks. The 2.5 rear shocks feature a 2.5-inch impact extruded aluminum body, a massive 7/8-inch hard chrome plated heat-treated alloy steel shaft, an external reservoir design that separates shock oil from high-pressure nitrogen, a standard DSC (Dual Speed Compression) adjuster, and are fully serviceable for a lifetime of use. Includes a 1-year Manufacturer's Warranty.
Overview
This 2-inch leveling kit for the Chevy Silverado and GMC Sierra 1500 (2019–2026) 4WD is designed to improve stance, performance, and capability while providing clearance for up to 33-inch tires. Up front, the kit includes FOX 2.5 Factory Series remote reservoir coil-over shocks with DSC (Dual Speed Compression) adjustment and heavy-duty tubular upper control arms. The rear utilizes complementary FOX performance shocks for a smooth ride. DSC adjustment on the FOX 2.5 coil-overs allows tuning of high-speed and low-speed compression damping via two clearly defined knobs, providing added control on-road and the ability to dial in more aggressive damping off-road.

- Can be used on Trail Boss / AT4 models, but will net 0-inch lift.
- All aftermarket wheels should be test fit prior to mounting the tire to ensure proper clearance to the brake caliper. Some wheel profiles will not clear the brake caliper. These can be test fitted before the vehicle is lifted in a stock condition.
