4 Inch Lift Kit | FOX 2.5 Performance Elite Coil-Over | Chevy Silverado or GMC Sierra 1500 (25-26) 4WD | Diesel

Built for diesel Silverado and Sierra 1500 owners who want 33-inch tires, genuine off-road capability, and predictable on-road handling — this 4-inch BDS lift kit pairs FOX 2.5 Performance Elite coil-overs up front with a rear block lift to deliver 4 inches of front and 3 inches of rear clearance. CNC-machined steering knuckles correct your geometry at the taller ride height so your truck tracks true.

What you get up front

• FOX 2.5 Performance Elite Coil-Overs — Twin-tube shocks with remote reservoirs, DSC adjusters for 10 low-speed and 12 high-speed compression settings, and race-proven tuning that soaks up rock gardens without sacrificing highway comfort.
• 1/4-inch Thick Steel Crossmembers — Laser-cut, high-clearance design maximizes tire and obstacle room while the integral skid plate system bolts into a rigid subframe for protection.
• CNC-Machined Ductile Iron Steering Knuckles — Corrected for caster and geometry at your new ride height; ESC-compatible tie rod ends maintain steering feel and ABS function.
• Sway Bar Drops, CV Spacers & Brake Line Brackets — Complete front assembly with bump stop extensions and fasteners — nothing left behind.

Out back

Heavy-duty lift block installs in place of your factory block, preserving ride quality and load capacity. Paired with premium FOX 2.0 Performance Series shocks, new u-bolts, and brake line brackets for a finished rear that matches your new stance.
