QA1’s 2.5" I.D. high travel coil springs are built for drivers who want maximum suspension movement, predictable handling, and long-term durability. By using high-tensile chrome silicon alloy wire with fewer coils, these springs compress farther without reaching coil bind, giving you more usable suspension travel. The linear spring rate keeps performance consistent throughout the stroke, making these springs ideal for street, track, autocross, and off-road use. Lightweight construction, a silver powdercoated finish, and QA1’s lifetime warranty make them a reliable choice for any coilover setup.
