QA1 20.30 Eye-B/Eye-B V 4-650 Shock Large Aluminum Coilover 13.38

QA1 has a solid reputation for making performance suspension components, and this 6Q Series twin tube coilover shock is a great example of their work for circle track racing. It's built with a large aluminum body and features a rebound adjustable valving system, allowing you to fine-tune your suspension's response. The shock measures 13.38 inches in overall length and uses eye-to-eye mounting with a 4-650 spring rate, making it suitable for a variety of setups.

What sets this shock apart is its focus on ease of maintenance and adjustability for racers. The gland is designed with relief cuts and a hyper screw port, which simplifies the process of filling and bleeding the shock during assembly. Plus, the compression tube uses a slip-fit design that makes rebuilding the shock straightforward. QA1 also includes an upgraded seal kit to help minimize leaks, especially when dealing with high rebound forces. Even better, the 6Q shocks are designed so racers can re-valve and rebuild them quickly with basic tools right at the track or in the shop.

You'll also find that the closure nuts are laser-engraved and black-anodized, which makes reading the serial numbers and valving settings much easier, even in bright sunlight or dim garage conditions. This attention to detail means you can spend less time fiddling with your suspension and more time racing.
