A-Body Lowering Spring Height Guide

UMI Performance A-Body Linear Springs

At UMI, we specialize in high-performance springs. Designed with a top Sprint Cup chassis engineer, our springs use premium 5160 CrSi wire for the front and 9254 CrSi wire for the rear, offering linear rates of 530 lb/in and 130 lb/in respectively. This ensures consistent handling, reduced body roll, and eliminates the "floating" feel in A-body vehicles.

Finished with a durable black powder coat and proudly made in the USA, UMI springs are the benchmark in muscle car suspension. Experience superior performance with UMI.
