ReadyLift - 6" MAX3.3 Lift Kit w/ Falcon 3.3 Shocks - 2021-2024 Ford F-150 (4WD) - 42-21640

6" MAX3.3 suspension system with Falcon 3.3 Fast Adjust shocks that delivers first-class ride, big tire clearance, and an aggressive lifted stance for the 2021-2024 Ford F-150 4WD.

ReadyLIFT's 6" MAX3.3 Suspension System for the Ford F-150 combines Falcon 3.3 Fast Adjust dampers with heavy-duty 1/4" steel plate front and rear crossmembers, durable lifted cast knuckles, and machined strut spacers. The system corrects suspension, steering, and driveline geometry to maintain on-road handling while improving strength and off-road capability. A fabricated 4" tall rear block with factory-style U-bolts sets the rear lift, and ReadyLIFT's upgraded upper control arms add strength, travel, and corrected alignment.

Fits: 2021-2024 Ford F-150 4WD. Does NOT fit vehicles equipped with CCD (Continuously Controlled Damping), 2WD models, Raptor, or F-150 diesel.
