6" Big Lift With Falcon 2.1 Rear Shocks 2021-2026 Ford F-150 (part number 44-21621).

ReadyLIFT's proven 6-inch Big Lift Kit for the 2021-2026 Ford F-150 4WD now features Falcon 2.1 Monotube rear shocks, replacing the previous Falcon 1.1 shocks. Built for enthusiasts who want a commanding stance without sacrificing everyday comfort, this updated system combines clearance for larger tires with controlled handling on the highway and beyond.

Heavy-duty steel crossmembers, lifted knuckles, and tapered strut spacers deliver 6 inches of front lift while correcting suspension, steering, and driveline geometry. Fabricated 4-inch rear blocks complete the balanced stance. Falcon 2.1 Monotube rear shocks for comfort, stability, and ride control. 1/4-inch steel front and rear crossmembers and heavy-duty lifted knuckles. Tapered front strut spacers for proper strut-angle correction.

Full-coverage 3/16-inch steel differential skid plate. HD alignment cam bolts and carrier bearing drop brackets for two-piece drivelines. Fabricated 4-inch rear blocks with factory-style U-bolts.

Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.

Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.
