Description

QA1's Proma Star Coil-Overs provide the benefits of coil-over shocks for a wide array of vehicles, including custom chassis and those without direct-fit options. They are available with 3" to 9" of stroke and single- or double-adjustable valving to upgrade ride quality and performance. The shock and included hardware allow for quick and easy ride height adjustment. Users must add a 2.5" spring of appropriate length and spring rate. Double-adjustable shocks offer independent compression and rebound tuning, suitable for street, drag, and road course applications.
