Coil Spring - 2.5in x 9 500#

The Coil Spring - 2.5in x 9 500# by QA1 is a precision-engineered suspension component designed for vehicle builders and performance enthusiasts who require reliability in custom suspension setups. This coil spring is ideal for applications ranging from lowered street rods to competition off-road platforms, providing consistent spring rates and predictable handling characteristics.

With a spring rate of 500 pounds and a free length of 9 inches, this coil spring offers moderate resistance suitable for mid-range suspension geometry on compact to mid-size vehicles. The 2.5-inch coil diameter allows for easy integration with standard shock absorber mounting locations and suspension brackets. QA1 utilizes high-grade steel wire and precision coiling processes to ensure consistent preload and minimal harmonics, contributing to an extended service life under repeated stress cycles.

This spring is particularly beneficial for builders working on independent front suspension (IFS) conversions, custom A-arm assemblies, or modular suspension platforms, where a direct replacement or custom-tailored spring rate is essential. Mechanics and suspension tuners appreciate the reliability and performance of QA1's coil springs in various applications, ensuring optimal handling and ride quality.
