The Belltech rear axle flip kit for 2009–2013 Ford F-150 standard cab short bed (4-inch rear drop) relocates the axle from beneath to above the leaf spring to achieve a lowered stance. Engineered per application from high-quality steel with a durable powder-coat finish, these kits include Grade 8 hardware and, in most cases, frame-rail C-notches. The design aims to provide a more aggressive drop while retaining OEM leaf spring mounting.
