4 Inch Lift Kit | Chevy Silverado or GMC Sierra 1500 (25-26) 4WD | Diesel

Built for diesel Silverado and Sierra 1500 owners who want 33-inch tire clearance and better stance without sacrificing on-road geometry. This 4-inch lift kit combines a reinforced crossmember, strut spacers, and heavy-duty rear blocks to deliver 4 inches up front and 3 inches out back. BDS engineered this kit to preserve steering angles and ESC compatibility — so your truck handles as well as it looks.

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

• Strut spacers — top-mounted design that adds 4 inches of height while keeping factory strut geometry intact.
• High-arched 1/4-inch steel crossmembers — laser-cut for a perfect fit, paired with a front skid plate that bolts together for rigid protection off-road.
• CNC-machined ductile iron steering knuckles — correct caster and steering geometry at the new ride height, maintaining ESC system compatibility and tie-rod angles.
• Sway bar drops, brake line brackets, CV spacers, and bump stop extensions — everything needed for a bolt-together front end.

Out back

Heavy-duty lift blocks replace the factory units, adding 3 inches of height while retaining ride quality and load capacity. New u-bolts, brake line brackets, and precision-tuned shocks complete the rear suspension.

Pick your shocks

• BDS NX2 Nitro — comfortable daily driver with 14-stage compression tuning; the best value for stock-like comfort on street and light trail use.
• FOX 2.0 Performance Series — premium option with smooth damping and excellent off-road control; choose strut spacer or full coil-over pairing.

Important notes

• Maximum tire size: 33 x 12.5. Larger tires may require trimming or cause clearance issues.
• This kit is engineered for 2025–2026 diesel Silverado 1500 and Sierra 1500 4WD models. Fitment varies by trim and year — confirm your vehicle code before ordering.
• Factory air suspension, RamBox (if equipped), and other OE options may have fitment restrictions; contact us to verify compatibility with your truck's build.

Why customers pick this at Road Runner

• BDS suspension warranty backed locally — your kit is installed by technicians who do these every week and stand behind the work.
• Corrected geometry out of the box — no clunky compromises; your truck steers straight and rides predictably at full lift height.
• True skid plate coverage — not a bolt-on afterthought; the crossmember system creates a rigid subframe for real off-road protection.
• Mount and balance available on most kits — we keep common shocks in stock so you drive out lifted the same day you call.
