Skyjacker 3 In x 12 In x 200lb Universal Coilover Coil Springs

If you're looking to dial in the suspension on your custom build or upgrade, these Skyjacker coilover springs are a solid option. They're designed to provide a specific ride height and spring rate, which is crucial for getting the handling characteristics you want. This particular spring measures 3 inches in height and has a spring rate of 200 pounds per inch, meaning it will compress 1 inch under a 200-pound load. This is a common setup for achieving a mild lift and improved off-road responsiveness while maintaining comfortable on-road handling.

Skyjacker uses high-tensile chrome silicon wire for these springs, which is a strong material to start with. The manufacturing process includes shot peening, where the steel is blasted with hard pellets at high speed. This compresses the surface of the steel, increasing its tensile strength and making the spring more durable and resistant to fatigue. They also go through a preset process, compressing the spring completely until the coils touch. This eliminates any built-in stress and helps prevent sagging over time, ensuring the spring maintains its intended height and rate for longer. The ends are closed and ground flat, which helps distribute the spring force evenly and makes installation easier.

These springs are finished with a black powder coat that's designed to resist corrosion and look good. They're made in the USA, and each spring is cycle tested to ensure it meets Skyjacker's standards for performance and longevity. Because these are universal coilover springs, you'll want to confirm they're the right size and rate for your specific application and shock absorber body.
