Product details
UMI P/N 4054 is used to provide a double shear upper attachment point for a true 2-1/2” racing coilover shock and spring. Most applications will use an industry standard 7” stroke double rod end shock and 12” x 2-1/2” diameter coilover spring. The bracket bolts to the upper a-arm mount in order to properly locate the unit for welding. Prototyping was completed using Afco Pro-Tour Elite shocks.
