QA1 20.30 Eye-B/Eye-B V 4-500 Shock Large Aluminum Coilover 13.38

QA1 is a well-known name in performance suspension, and their 6Q Series shocks are built with racers in mind. This particular shock absorber is a twin-tube, rebound-adjustable coilover designed for circle track applications. It features a large aluminum body and a 13.38-inch overall length, with eye-to-eye mounting points. The focus here is on adjustability and ease of maintenance, so you can spend less time wrenching and more time on the track.

What sets these shocks apart is how easy they are to work with. The gland has relief cuts and a special port that makes filling and bleeding the shock simple during assembly. If you need to change the valving, QA1 designed these shocks so racers can re-valve and rebuild them quickly using common tools. Plus, an upgraded seal kit helps cut down on leaks, which is especially important when you're dealing with high rebound forces. The compression tube uses a slip-fit design, which also makes the rebuilding process more straightforward.

You'll also notice laser-engraved, black-anodized closure nuts. These aren't just for looks; they make it easy to read the serial numbers and valving settings, whether you're at the track or back in the shop. This attention to detail means you can fine-tune your suspension with confidence.
