Transform your classic GM A-Body's rear suspension with the UMI Performance 4057 Rear Coilover Kit. This innovative, bolt-in system provides complete adjustability for ride height, spring rate, and damping, allowing you to fine-tune your vehicle's performance for any application, from drag racing to autocross and road course duty. The kit features a reinforced upper mount that requires minimal modification (one additional hole) for installation and securely holds a 2-1/2" racing coilover with a double-shear mount. The robust lower brackets bolt directly over the stock rear lower control arm mounts, utilizing existing shock holes and potentially requiring an additional hole depending on your specific model.
This rear coilover kit is the ultimate solution for enthusiasts looking to significantly upgrade their A-Body's handling, traction, and adjustability. By allowing precise tuning of the suspension geometry, you can optimize your vehicle for peak performance on the street or track. Elevate your driving experience with UMI Performance's cutting-edge suspension components, available at GGCRACING.
