UMI Performance 3623-1 Rear Coilover Conversion Kit for GM B-Body

The UMI Performance 3623-1 is a complete bolt-on rear coilover conversion kit designed specifically for 1978-1996 GM B-Body vehicles. This 100% American-made kit eliminates the factory spring-and-shock setup in favor of a modern coilover suspension system, offering both adjustable ride height and tunable damping control.

Key Features:

• Viking brand coilover shocks with adjustable compression and rebound damping
• High-quality Viking coil springs matched to application
• Laser-cut US steel components with precision jig welding
• Double shear upper and lower mounting design for maximum strength
• Bolt-on installation with no welding required
• Upper mount installation requires simple drilling with standard 3/8" drill bit
• Engineered to fit factory GM B-Body axles
• Fully adjustable ride height capability

This coilover kit provides the foundation for improved handling and a custom stance while maintaining the reliability of American-made construction. The adjustable damping allows you to fine-tune your suspension for street driving, spirited cornering, or track use. Ideal for Chevrolet Caprice, Impala SS, and other GM B-Body platform vehicles.
