QA1 20.30 Eye-B/Eye-B V 3-500 Shock Large Aluminum Coilover 13.38

QA1 is well-known for making performance suspension parts, and this 6Q Series twin tube shock absorber is a solid example of their work. It's a large aluminum coilover designed for circle track racing, featuring rebound adjustability to help you fine-tune your car's handling. The extended length is 13.38 inches, and it uses eye-to-eye mounting with a 3-500 valving code.

What makes these shocks stand out is how easy they are to work with. The gland has relief cuts and a special port, which simplifies filling and bleeding when you're assembling them. Plus, QA1 designed these so racers can re-valve and rebuild them quickly with basic tools, right at the track if needed. An upgraded seal kit helps reduce leaks, especially when you're running high rebound settings. The compression tube uses a slip-fit design, which also makes rebuilding a straightforward process.

You'll also notice the laser-engraved, black-anodized closure nuts. They make it easy to read the serial numbers and valving information, which is a handy detail whether you're at the track or working in the shop.
