What is the purpose of shot peening these springs?

Shot peening involves blasting the spring surface with hard steel pellets at high velocity. This process compresses the steel's surface, which increases its tensile strength and makes the spring more durable and resistant to fatigue.

Why are the ends of the springs ground flat?

The ends are ground flat and perpendicular to the spring axis to create a uniform surface. This ensures an even distribution of spring force against the mounting assemblies, which improves ease of installation and consistent spring performance.

What does the '300lb' rating mean for these springs?

The 300lb rating refers to the spring rate, meaning it takes 300 pounds of force to compress the spring by one inch. This rate is chosen to provide a balance between off-road responsiveness and comfortable on-road handling for many applications.

Product Details

Starting with high-tensile chrome silicon wire, these Skyjacker coilover springs are built for consistent performance. The 300lb spring rate is designed to offer a good balance between off-road responsiveness and comfortable on-road handling, making them a solid option for many universal applications. They measure 2.5 inches in diameter and 14 inches in length, fitting into many common coilover shock bodies.

Skyjacker uses an advanced shot peening process, blasting the steel with hard pellets at high velocity. This compresses the surface, increasing tensile strength and durability. The springs are also preset by compressing them fully until the coils touch, which eliminates fatigue and prevents sagging over time. This attention to detail means you get a well-built spring that holds its intended height and rate.

The ends of these springs are ground flat and perpendicular to the spring axis, ensuring an even distribution of force against the mounting surfaces. This not only improves ease of assembly but also helps maintain consistent spring action. Finished with a durable black powder coat, these springs resist corrosion and look sharp. They are made in the USA and have undergone cycle testing to ensure quality.
