Product details
If you want the best for your ride, look no further. The 2021+ Ford F150 2WD and 4WD flip kit expertly relocates the original leaf springs below the axle. By doing so, we achieve a rear lowered ride height of 4.5" for the 2WD and 5.5" for the 4WD. The kit is powder-coated to prevent corrosion caused by dirt or debris. We feature front leaf spring hangers to reposition the mounting point of the springs, pinion positioning axle saddles with pinion shims, high grade 9/16" U-bolts, notched U-bolt plates, U-bolt spring pads, and new shackles with bushings that help cancel noise and absorb vibrations. All precision designed to fit flawlessly with the original leaf springs. Build the ride you need with Belltech. Belltech flip kits are designed to offer a more aggressive drop for that traditional "slammed" appearance. A lowered center of gravity and no modification to the oem leaf spring aid in retaining the oem ride quality. 2021-2026 Ford F150 2WD/4WD FLIP KIT 4.5" DROP 6451 FLIP KIT | 4.5 INCH DROP - 6451 4.5" Drop Flip Kit
