The perfect ride for your rod...

Designed around the PromaStar AL shock, this line of QA1 coilover shocks applies deflective disc valving to provide the best self-adjusting ride possible. Such heightened valve sensitivity allows for better shaft speed control to precisely vary the shock resistance according to road conditions. With a 5/8" chrome-plated solid piston rod, which offers greater strength over hollow piston rods of smaller diameter, rod flex is eliminated and valving consistency is increased.

The double-lip seal design of these shocks reduces leakage while a secondary wiper seal prevents road grime from reaching the seals. Each adjustable shock includes an anodized aluminum spring cap, seat, locking ring, and one-piece bushings. The shocks are 100% dyno-tested, and they are available anodized or polished.
