About this part

Air Spring Kit, fitment-checked

An air spring kit for 2017–2022 Ford F-250 and F-350 Super Duty 4WD, XL through Limited. Before assembly, check which of the three factory rear block heights — 1, 2, or 3 inches — your truck has, because that determines how the lower brackets stack. Bags support up to 5,000 lb of load. Minor drilling is required, and the kit does not change the truck's tow rating.

Fitment covers XL, XLT, Lariat, King Ranch, Platinum, and Limited on the 2017–2022 F-250 and F-350 Super Duty in 4WD. The install detail worth knowing up front: three rear block heights were used on these trucks — 1 inch, 2 inch, and 3 inch — and the block under your springs sets how the bottom mounting brackets are assembled. Measure before you start. Minor drilling is required and a downloadable installation guide is available. Air springs carry a Limited Lifetime warranty.
