BDS 4 Inch Lift Kit | Chevy Silverado & GMC Sierra 1500 (2025-2026) 4WD Diesel | FOX 2.0 Rear / Strut Spacer Front

Configured with FOX 2.0 Performance Series rear shocks and front strut spacers. FOX 2.0 rear shocks feature a 2-inch impact-extruded CNC-machined 6061-T6 anodized aluminum body, a 5/8-inch hard chrome-plated heat-treated alloy steel shaft, race-developed high-flow piston, application-specific valving, and an internal floating piston (IFP) monotube reservoir design.

Overview

BDS Suspension's 4-inch lift kit is engineered to improve the stance, performance, and off-road capability of the 2025–2026 Chevy Silverado 1500 and GMC Sierra 1500 (4WD, Diesel and 2.7 Gas models). The kit provides clearance for tires up to 33 inches and includes everything necessary for a comprehensive front and rear suspension lift.

Up front, the kit utilizes top-mounted strut spacers, high-arched 1/4-inch thick steel crossmembers, multipiece differential relocation brackets, and heavy-duty skid plates for off-road protection. Steering geometry is corrected at the new ride height with CNC-machined ductile iron steering knuckles and replacement tie rod ends, 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, retaining ride quality and load capacity. New U-bolts and brake line brackets are included, along with your choice of precision-tuned NX2 Nitro or FOX 2.0 Performance Series rear shocks.
