QA1 63 Series Sealed Threaded Body Twin Tube Shock Absorber - 7in Stroke - 5-850 Valving - Aluminum

This is the QA1 63 Series sealed, non-rebuildable twin tube shock absorber. It's built with a threaded aluminum body and a 7-inch stroke, featuring 5-850 valving. This shock is commonly used in coil-over setups, especially for dirt and asphalt track racing applications like late models or modifieds. The twin tube design is known for providing excellent feel and grip, particularly in conditions where traction is limited.

QA1 builds these shocks as a spec unit, meaning they are designed to control costs for specific racing series or tracks, making them a solid option for sanctioning bodies. Each shock is individually dyno'd and serialized to ensure it meets performance standards right out of the box. The sealed aluminum body construction means it's built to last without needing to be rebuilt, offering a straightforward performance solution.
