Ford F-150 Lowering Kit Fitment Guide

The F-150 has run several front suspension designs since 1997, and the lowering hardware changes with each one. Earlier 2WD trucks (1997-2014) use drop spindles or lowering coils up front and an axle flip kit in the rear, which is why those kits are cheaper but more labor-intensive to install. From 2015 on, most kits switch to a strut- or coilover-based front end that is adjustable within a range instead of a fixed drop.

4WD F-150s cannot use spindle or flip-kit style drops because of the front differential and driveshaft clearance, so 4WD lowering is limited to adjustable strut kits (front) paired with a shackle/flip rear kit, and the available drop is smaller than on 2WD trucks of the same generation.

On a 2015-2026 truck, a 2WD front end can go as low as 3-5 inches with a spindle or coilover kit, while the 4WD front strut kit on the same generation tops out around 3.5 inches. Rear drop is similar on both drivetrains because the rear axle and leaf springs don't change between 2WD and 4WD.

If you're shopping a lowering kit for a different truck, the same 2WD/4WD gap applies to most body-on-frame pickups, not just the F-150.

A front drop beyond about 2 inches on a strut-based F-150 (2015+) usually pushes camber outside factory spec, so budget for an alignment with camber bolts or offset upper control arms after install. On 1997-2014 spindle kits, the drop spindle itself is machined to keep the factory camber curve closer to stock, which is one reason those kits remain popular despite being the older design.

Rear flip-kit drops of 5 inches or more reduce up-travel before the frame or driveshaft contacts the axle; kits in the 5.5-7.5 inch rear range are usually sold with shortened bump stops or a bump stop spacer for this reason. Stock-diameter wheels and tires generally clear a 3/5 drop; kits built for larger drops (MaxTrac's 2015-2020 3/5 kit, for example) explicitly call for 22-inch or larger wheels with limited backspacing to clear the lowered control arms and spindle.

Match the kit to your exact cab/drivetrain listing, not just the model year range - several kits for 2015-2026 trucks are sold in separate 2WD and 4WD part numbers with different drop specs, and some current-generation kits exclude trucks with the Max Trailer Tow Package. If you're set on an adjustable ride height instead of a fixed drop, see our air suspension overview for how F-150 owners run air springs instead of or alongside a lowering kit.
