UMI 64-72 GM A-Body Coil Over Conversion Brackets Kit -1in to +1in Ride Height - 250lb Spring Rate

If you're looking to fine-tune the suspension on your classic GM A-Body, this UMI coilover conversion bracket kit is a solid option. It's designed to let you adjust ride height, spring rate, and damping, giving you a lot of control over how your car handles. This kit is built for models like the Chevrolet Chevelle, Buick Skylark, and Pontiac GTO from 1964 through 1972, allowing for a ride height change of up to an inch up or down.

The upper mount is beefed up to handle a 2-1/2 inch racing coilover with a double-shear setup, which is crucial for stability under load. The lower brackets were designed using FEA analysis to make sure they're strong and bolt directly onto your existing Quick Performance rear lower control arm mounts. A really useful feature is the two-hole trailing arm adjustment, which lets you dial in the instant center location across three different positions. This means you can really calibrate your suspension for specific driving conditions, whether that's street cruising or drag racing. Keep in mind that welding is recommended for drag racing applications to ensure maximum stability.

This kit is made with 100% US materials and manufactured right here in Philipsburg, Pennsylvania. It's a well-built setup that gives you the adjustability needed to get your classic car handling just the way you want it. When installing, it's a good idea to put the brackets on first and measure from center to center at ride height to make sure you order the correct shocks for your setup.
