The QA1 Proma Star Series coil-over shock absorber brings coil-over performance to a wide range of custom chassis and suspension builds where a direct-fit shock is not available. This single adjustable model uses a bushing mount and measures 10.125in collapsed and 14in extended. A single adjuster tunes rebound and compression together for a balance of ride comfort and performance. The poly bushing mount includes sleeves and helps reduce noise, vibration, and harshness. The included hardware kit allows quick ride height adjustment, and the shock accepts a 2.5in diameter coil-over spring in the appropriate length and rate, sold separately. Each unit is machined from aluminum, dyno tested, serialized, and built in the USA.
