2.5" 2025-2026 Chevy Silverado 1500 Trail Boss 4WD (w/Diesel Engine) Fox Performance Elite Coilover Lift Kit by BDS Suspension

The BDS Suspension BDS1856PES/PSS 2.5-inch premium coil-over suspension lift kit for the Chevy Trail Boss Silverado 1500 truck allows for the fitment of up to 35-inch diameter tires, providing an awesome off-road look. Featuring Fox 2.5 Performance Elite remote reservoir coil-overs. These Fox 2.5 Coil-overs will enhance ride quality and handling in both on-road and off-road conditions.

This lift kit also features 1/4-inch-thick steel, laser-cut, high-clearance crossmembers designed to provide maximum clearance and a rock-solid mounting point for the factory lower control arms. Three-piece heavy-duty front skid plates connect the cross members, protecting steering and driveline components. Correct steering geometry is maintained using new ductile iron steering knuckles that keep the ESC system compatibility, along with tubular upper control arms. CV axle angles are minimized using a multi-point front differential relocation system. The rear end is lifted using 3-inch-tall axle blocks (replacing 2.5-inch factor blocks) with extended U-bolts.

Fox 2.5 Performance Elite Coil-overs with DSC Remote Reservoirs - These top-of-the-line adjustable coil-overs feature a 2.5-inch diameter CNC-machined 6061-T6 hard-anodized aluminum body that resists rust and allows for excellent heat dispersion. The remote reservoir increases oil capacity and houses the DSC (dual speed compression) adjuster knob. This allows you to easily adjust the ride softness or firmness of your coil-overs to match the current terrain and vehicle load by changing the high-speed and low-speed compression settings with the turn of a dial.

Choose your rear shocks, either FOX 2.0 Performance Series or 2.5 Performance Elite! The FOX 2.0 Performance Series rear shocks are built with a 2-inch impact extruded aluminum body, internal floating piston (IFP) monotube design, CNC-machined 6061-T6 aluminum ends, and a large 5/8-inch chrome-plated alloy steel shaft. Or upgrade to the Fox 2.5 Performance Elite, which features a 2.5-inch diameter aluminum body with a massive 7/8-inch chrome-plated shaft and DSC (Dual Speed Compression) adjuster, allowing you to fine-tune your ride from smooth to firm.
