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 offer increased compression travel without reaching coil bind. The linear spring rate provides predictable handling through the entire stroke, making them ideal for racing, off-road use, or high-performance street driving. Lightweight construction, a silver powdercoated finish, and QA1’s lifetime warranty ensure dependable performance in any setup.
