4 Inch Lift Kit | FOX 2.5 Performance Elite Coil-Over | Ford F150 (15-20) 4WD

Built for F-150 owners who want maximum tire clearance without sacrificing ride quality — this 4-inch lift kit pairs BDS-engineered coil-over suspension with your choice of FOX shock tiers, letting you run larger rubber while keeping your truck planted on road and trail. You get corrected caster geometry, factory-matched geometry preservation, and the ability to fit up to 37-inch tires.

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

• BDS coil-over struts — engineered to handle 37-inch tires without binding, with integrated rebound and compression control.
• Upper and lower control arms — welded from nodular iron and factory-tuned for geometry correction that restores your steering feel.
• Caster-correcting brackets — keeps your wheels pointed straight and your scrub radius stock.

Out back

FOX rear coil-overs with adjustable damping complete the 4-inch stance, matching your front geometry and letting you dial in compression and rebound to suit your driving style — highway cruising, off-road abuse, or both.

Pick your shocks

• FOX 2.0 Performance Series — a proven daily-driver workhorse, handles larger tires and moderate terrain without breaking the bank.
• FOX 2.5 Performance Elite — full-featured DSC (Dual Speed Compression) adjusters, better off-road isolation, and smoother on-road damping across the entire suspension travel.

Important notes

• F-150 models equipped with factory air suspension are not compatible — confirm your truck runs conventional coil springs before ordering.
• OE wheels with offset in the 44–50 mm range work best; deeper backspacing may require slight fender trimming to clear 37-inch tires.
• Factory driveshaft geometry is preserved; however, driveline angle should be inspected if running 37-inch tires on lifted 4WD trucks.
• Vehicles with factory electronic suspension damping (Terrain modes, etc.) will function normally with this mechanical system.
