Upgrade a custom chassis or suspension system with the QA1 Proma Star Series Coil-Over Shock Absorber, part number qapDS702. Designed for applications that require flexible installation and precise ride-height control, this single-adjustable shock features bushing mounts at the top and bottom and offers a compressed height of 13 inches with an extended height of 19.5 inches. Its adjustable design helps you achieve the stance and suspension performance required for your vehicle.
The Proma Star coil-over system allows you to tune overall ride quality and handling with a single adjustment knob. It is well suited for street-driven vehicles, custom builds, and other applications where direct-fit shock options are unavailable. Add a compatible 2.5-inch coil-over spring with the appropriate length and spring rate to complete the setup. The included hardware kit simplifies installation and ride-height adjustment, while the bushing configuration helps reduce noise, vibration, and harshness compared with rigid mounting arrangements.
QA1 manufactures its Proma Star shocks in the USA and dyno tests them to help ensure consistent performance and quality. The shock is backed by QA1's Limited Lifetime Warranty when registered before installation. Confirm that the selected shock provides adequate suspension travel to prevent overextension or bottoming out. When using a stock spring pocket, verify that the desired ride height can be achieved while maintaining sufficient shock travel. Available spanner wrenches and thrust bearings can make ride-height adjustments easier. This product may contain chemicals known to the State of California to cause cancer or reproductive harm.
