4" 2025-2026 GMC Sierra 1500 4WD Lift Kit by BDS Suspension

Enhance the performance, style, and off-road capability of your GMC Sierra 1500 with the BDS1851H/FS/FSR 4-Inch Suspension Lift Kit. Designed to deliver a leveled, aggressive stance and clearance for up to 33-inch tires, this kit is engineered to handle everything from rugged trails to daily driving with confidence and control.

The front end is outfitted with top-mounted strut spacers (or can be upgraded to Fox snap-ring coilovers), heavy-duty 1/4-inch thick high-clearance crossmembers, CNC-machined ductile iron steering knuckles, and a multi-piece differential relocation system. When combined with sway bar drops, bump stop extensions, CV spacers, brake line brackets, and a skid plate system, this lift kit provides maximum ground clearance and superior protection while maintaining factory steering geometry and ESC system compatibility.

At the rear, a heavy-duty lift block and precision-tuned shocks—either the robust NX2 Nitro Series or premium FOX 2.0 Performance Series—ensure balanced performance, ride comfort, and full load capacity. Choose between strut spacer or FOX 2.0 Performance Series front shock options for tailored ride quality and performance gains. Whether you’re cruising the highway or heading off the beaten path, BDS Suspension’s proven high-clearance design delivers strength, reliability, and the stance your truck deserves.
