UMI 64-72 GM A-Body Coil Over Conversion Brackets Kit -1in to +1in Ride Height - 225lb Spring Rate

If you're looking to fine-tune the suspension on your classic GM A-Body, this UMI Performance coilover conversion kit is designed to give you a wide range of adjustability. It allows you to dial in your ride height, spring rate, and damping, plus adjust the trailing arm position to precisely calibrate the instant center. This kit is built for vehicles like the Chevrolet Chevelle, Pontiac GTO, and Buick Skylark from 1964 through 1972.

The upper mount is reinforced to securely hold a 2-1/2 inch racing coilover, and the lower brackets were designed using FEA analysis for strength and then bolted directly onto your existing control arm mounts. You get a two-position adjustment for the trailing arm height, which lets you tune the instant center location. This kit is made in the USA with materials sourced from the US, reflecting a commitment to solid construction. While it's a bolt-in kit for the most part, welding is recommended for drag racing applications to ensure maximum stability.

It's a good idea to install the brackets first and then measure from center to center at your desired ride height. This will help you pinpoint the exact shock part numbers you'll need. This kit is designed to work with Quick Performance rear setups, offering a comprehensive solution for upgrading your classic muscle car's handling.
