QA1 Proma Star Series Coil-Over Shock Absorber - Double Adj. - Bushing Mount - 9.5in/12.75in - Alum

QA1 is known for making performance suspension parts that help racers and custom builders get the most out of their vehicles. If you're building a custom chassis or need a coil-over shock for a vehicle where direct-fit options are hard to find, the Proma Star Series is a solid choice. This double-adjustable shock absorber lets you independently tune both compression and rebound damping, giving you precise control over your ride quality and handling. It's designed to work with a 2.5-inch spring, which you'll need to select based on your vehicle's weight and intended use.

This particular shock features a compressed length of 9.5 inches and an extended length of 12.75 inches. The bushing mount configuration, which includes 1/2-inch and 5/8-inch sleeves, helps reduce noise, vibration, and harshness (NVH) for a more comfortable ride. You can easily adjust the ride height using spanner wrenches and thrust bearings (sold separately) to achieve your desired stance. Because these are double-adjustable, they're ideal for drivers who want to fine-tune their suspension for everything from daily driving to serious track time on the street, drag strip, or road course.

All QA1 Proma Star shocks are proudly made in the USA and dyno-tested to ensure they meet performance standards. They also come with a Limited Lifetime Warranty for peace of mind. Remember to ensure your setup allows for adequate shock travel to prevent bottoming out.
