Skyjacker 3 In x 14 In x 300lb Universal Coilover Coil Springs

Skyjacker is well-known for their Softride coil spring technology, which aims for exact height and precise spring rates. This product, the 3" x 14" x 300lb Universal Coilover Coil Spring, carries that legacy forward, offering off-road responsiveness combined with smooth, consistent handling characteristics.

The process starts with high tensile chrome silicon wire. Each spring is then shot peened by blasting it with hard steel pellets at high velocities. This shot peening process compresses the surface of the steel, increasing its tensile strength. After that, each spring is preset by compressing it completely until the coils touch. This step removes fatigue and stress, helping to prevent sagging over time. Every coil spring has also endured a cycle test to ensure quality. The ends are closed and ground flat, creating a perpendicular surface to the spring axis for even force distribution and easier assembly.

These springs are made in the USA and feature a durable black powder-coated finish that resists corrosion. They are designed for universal fitment on coilover systems.
