Proma-Star C/O Shock - Single Adjustable

The Proma-Star C/O Shock - Single Adjustable from QA1 is a professional-grade twin-tube shock absorber engineered for vehicles requiring precise damping control and extended travel performance. Designed for street and strip applications, this single adjustable shock delivers the responsiveness needed for both daily driving comfort and competitive performance tuning. The 9.50-inch compressed and 12.63-inch extended length provides substantial travel range, making it ideal for suspension systems that demand reliability and adjustability without compromise.

Built with a 2.00-inch outer diameter aluminum body featuring threaded construction, the Proma-Star shock offers single-point adjustability that allows tuners to dial in compression damping to match specific driving conditions and vehicle setup. The twin-tube design separates working fluid from pressurized gas, enabling consistent performance across temperature ranges and extended use cycles. Natural aluminum finish provides corrosion resistance while the threaded aluminum construction ensures secure mounting compatibility with standard shock eyelet systems, delivering durability that withstands both street abuse and track demands.

This shock suits enthusiasts and professional installers seeking adjustable suspension geometry for street rods, muscle cars, and performance vehicles where fine-tuning handling is essential. Installation requires standard shock mounting points with compatible eyelet brackets; the threaded design and compact 3.68-pound weight make integration straightforward in most suspension systems. Whether upgrading a classic restoration or optimizing modern performance suspension, the Proma-Star single adjustable shock provides the control and adjustability professionals rely on for consistent results.
