Elevate your vehicle's rear suspension performance with the UMI Performance Bolt-In Viking Rear Coilover Kits. This rear coilover kit is designed to fit factory GM axle housings and offers enthusiasts a robust solution for enhancing handling and ride quality.
Crafted by UMI Performance, a trusted name in high-performance automotive components, this kit features adjustable valving with an impressive 361 settings. This allows for tailored damping to suit your specific driving style or track conditions.
The coilover kit includes twin-tube shocks and coilover springs with a spring rate of 225 lbs. per inch, finished in a sleek gray and silver combination that complements your vehicle's undercarriage.
Adjust your suspension height between 2.0 to 3.0 inches lowered to achieve a more aggressive stance and improved aerodynamics without compromising comfort.
With hardware included and no welding required for standard applications, installation is straightforward. However, if you plan on drag racing or use slicks, welding of bolted brackets is necessary for added security.
