Product Details
QA1 has a solid reputation for making performance suspension parts, and this 6Q Series shock is a great example of that. It's a large aluminum coilover designed for circle track racing, featuring rebound adjustability so you can fine-tune your car's handling. The 13.38-inch overall length and eye-to-eye mounting make it a straightforward component to integrate into your setup.
What really 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, which is a big help during assembly or if you need to service it. Plus, the compression tube uses a slip-fit design, further simplifying the rebuild process. QA1 also includes an upgraded seal kit to help prevent leaks, especially when you're dealing with high rebound forces. Even better, you can re-valve and rebuild these shocks yourself in minutes with basic tools, which is a huge advantage for racers who need to make quick adjustments at the track.
You'll notice the 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 quickly identify and adjust your shocks to get the performance you need.
