2021–2026 FORD F-150 4WD – 6" BIG LIFT KIT WITH FALCON 1.1 MONOTUBE REAR SHOCKS
ReadyLIFT is now shipping the all-new 2021–2026 Ford F-150 4WD 6" Big Lift Kit — delivering first-class ride quality, serious tire clearance, and a great-looking lifted stance all in one complete package. This kit is part of ReadyLIFT's new family of high-performance big lift kits engineered specifically for the F-150 4WD platform.
The 6" Big Lift Kit raises the front of your F-150 a full 6" while giving the rear a neutral, purpose-built stance — no more squatty rear end or awkward proportions. Every component is engineered to correct suspension, steering, and driveline geometry so your F-150 drives as good as it looks, on-road or off. Heavy-duty 1/4" steel plate front and rear crossmembers deliver unmatched strength for real-world driving conditions, while durable lifted knuckles and strut spacers open the door to running up to 35-inch tires with the right wheel setup.
Included in this kit is ReadyLIFT's industry-exclusive Falcon 1.1 Monotube performance rear shock (SKU 44-21620) — designed for customers who want the ultimate in comfort, control, and damping performance. Rounding out the kit: a fabricated steel 4" tall rear block delivers the correct amount of rear lift, while factory-style U-bolts make installation cleaner and easier.
Whether you're building a lifted street truck, prepping for larger tires and off-road use, or just want the ultimate F-150 stance, the ReadyLIFT 6" Big Lift Kit delivers.
