The USCT leaf spring perch is well designed for your specific needs. The correct width, length and height with precisely sized location holes to fit your leaf spring locating tab. Built as an exact factory replacement part, these will fit any differential housing with a standard 3.125 inch tube such as the Mopar 8.75 and Spicer Dana 60 rear. Please note: many other replacement perches use an incorrectly oversized center registration hole and require welding in a bushing to fit vintage muscle applications. The USCT spring perches are precisely engineered to fit correctly.
CNC cut and Precision CNC bent, the spring perches are manufactured in the US from thick 3/16" mild steel. Why do we make them out of thicker steel than the originals? Our philosophy is simple; nothing overbuilt ever broke.
Auto Metal Direct is a team of true car guys with years of experience in sheet metal reproduction, car restoration and paint/body work. We believe that quality is not subjective! Our mission is to provide the best customer experience for the Ford, Mopar and GM classic car markets - both in products and in service.
Our panels are made from proper gauge steel and include all correct-as-original clips, tabs, flanges, bends and seams. Each time a prototype body panel comes off of a new tooling, we test fit it on a car. The marked up prototype is then used to change and improve the tools, and a new prototype is produced. This procedure might be repeated multiple times but, once the part is finally approved, you can be assured of a quality part.
