The UMI flip kit for 1973–1987 GM C10 trucks lowers the rear approximately six inches by relocating the axle above the leaf spring and moving it slightly rearward to retain wheel centering. The kit includes brackets, stand-offs, heavy-duty U‑bolts, a lower leaf plate and polyurethane bump stops, all finished in gloss black powder coat. Made in the USA, it pairs with UMI shock relocation and specific shock options for a complete lowered setup.
