1964-1972 GM A-Body Coilover Handling Package

UMI Performance brings the best of both worlds together by combining our Stage 2 handling kit with four corner coilover ride height adjustability. The kit includes caster corrected upper and lower a-arms loaded with 1/2″ taller upper ball joints, heavy duty UMI sway bars with new end links and greaseable bushings, rear tubular upper and lower control arms, replacement rear end housing bushings, heavy duty tubular frame braces, plus all necessary hardware. Ride height is adjustable from 1″-3″ below stock and the Viking shocks feature 19 settings in both compression and rebound. 100% Made In USA.

***This kit is for lowering your car 1-3″ below factory. Contact support@umiperformance.com if planning stock or raised ride height. No refunds if you choose the base kit with lowered ride height then want your car to be tall”

***UMI 4057 IS DIRECT BOLT-ON ONLY WHEN USED WITH A GM AXLE HOUSING AND STOCK GM BRACKETS. AFTERMARKET HOUSINGS VARY WIDELY IN DESIGN AND LAYOUT, WHICH MEANS THE 4057 BRACKET WILL NOT BOLT ON. EMAIL SUPPORT@UMIPERFORMANCE.COM BEFORE ORDERING FOR AN AFTERMARKET AXLE***
