QA1’s 2.5" I.D. high travel coil springs are engineered for maximum suspension movement, consistent performance, and long-term durability. Built from high-tensile chrome silicon alloy wire with fewer coils, they compress further before reaching coil bind, allowing full use of available suspension travel. The linear spring rate provides predictable performance throughout the stroke, making them well-suited for racing, off-road, and high-performance street applications. A lightweight construction, silver powdercoated finish, and lifetime warranty ensure dependable long-term use.
