The Maxtrac MXT lowering kit with spindles is described for 2015–2020 Ford F-150 4WD applications and references a 3/4-inch lowering specification for certain models; the listing also notes a requirement for 22-inch rims or larger on some configurations. This kit groups spindles with lowering hardware and should be matched to appropriate wheels and brakes for safe fitment.
