What is the purpose of shot peening these springs?

Shot peening involves blasting the spring with hard steel pellets at high velocity. This process compresses the surface of the steel, increasing its tensile strength and making the spring more durable for long-term use.

How does the preset process benefit the spring?

The springs are compressed completely until the coils touch as part of the preset process. This removes any fatigue or stress from the spring material, which helps to eliminate sagging over time and ensures consistent performance.

What does the flat ground end configuration do?

The ends of the springs are ground flat and perpendicular to the spring axis. This creates a flat surface that allows for an even distribution of spring force to the shock assembly and also improves the ease of installation.

Product Details

Starting with high tensile chrome silicon wire, these Skyjacker coilover springs are built for consistent performance. The 3-inch diameter and 16-inch length, combined with a 250lb spring rate, are designed to work with many coilover shock assemblies. This specific spring rate offers a noticeable improvement in off-road responsiveness while maintaining smooth handling on the street, a hallmark of Skyjacker's Softride technology.

The manufacturing process includes shot peening, where the steel is blasted with hard pellets at high velocity. This compresses the surface of the steel, increasing its tensile strength and durability for a longer lifespan. Each spring is also preset by compressing it completely until the coils touch, which removes fatigue and stress, preventing sagging over time. The ends of these springs are closed and ground flat, ensuring they sit perpendicular to the spring axis. This flat surface allows for even distribution of spring force to the working assembly and makes installation easier.

These springs are made in the USA and finished with a durable black powder coat that resists corrosion. They have undergone cycle testing to ensure quality and are ready to be installed on your coilover setup.
