    UMI Performance's bolt-in rear coilover bracket kit is a complete mounting solution for a Quick Performance axle on the GM G-Body platform. The brackets use a multi-position design that allows fine tuning of ride height and shock location within plus or minus three quarters of an inch. Along with shock location adjustability, the 3054 provides five positions of trailing arm location adjustment to match Quick Performance adjustable lower control arm brackets. Minor drilling is required. The brackets are laser cut from 3/16 inch mild steel for a precise, consistent fit and are powder coated black for a long lasting finish. They pair well with the UMI 3055 shock tower brace. This kit is made in the USA from USA materials.
