Increase traction and add ride height adjustability to the rear of your 1964-1972 GM A-Body with a Coil-Over Conversion Kit from BMR Suspension. OE-style lowering springs can drop the vehicle, but do so at the expense of suspension and shock travel. By utilizing a conventional coil-over, the vehicle can ride at a lower ride height, while still retaining full suspension travel. BMR manufactures its Coil-Over Conversion Kits from CNC-laser cut, CNC-formed 1/4-inch steel plate for strength, lightweight, and precise fitment. These also give you five mounting positions for the coil-over shock. This allows for easy instant center and anti-squat changes, so you can fine-tune the car(TM) s rear suspension geometry. Whether you want to aggressively lower your A-body or you want the added suspension control you get with coil-overs, BMR makes it easy to add coil-overs to the rear of your car. Designed for street performance, drag race, and handling applications, BMR makes its coil-over brackets from strong 1/4-inch laser-cut steel plate. These plates simply bolt in place and allow for commonly available coil-over shocks to bolt in. This kit is designed to work with any coil-over with a 1.25-inch wide bushing and -inch bolt hole. When performance is a must, rely on BMR Suspension! BMR Suspension(TM) s CCK402 Coil-Over Conversion Kit is available in black hammertone and red powdercoat for long-lasting good looks. Installation time is 2-3 hours. Proudly made in the U.S.A.!
