QA1 63 Series Sealed Threaded Body Twin Tube Shock Absorber - 7in Stroke - 5-400 Valving - Aluminum

If you're building a race car or a serious track machine where controlling costs is as important as performance, this QA1 63 Series shock absorber is a solid option. It's a twin tube design, which generally offers a good feel for the road or track surface, helping you maintain grip and control. This particular shock has a 7-inch stroke, a compressed length of 13.38 inches, and an extended length of 20.30 inches, making it suitable for a variety of suspension setups.

What sets this shock apart is its sealed aluminum body. The aluminum construction helps with heat dissipation, and the sealed design means it's built to handle demanding conditions without losing performance. Each shock is individually dyno-tested and serialized right here in the USA, so you know you're getting a well-built part that's ready to go. The 5-400 valving is a specific setting that works well for many track applications, especially for sanctioning bodies that want to keep budgets in check while ensuring reliable performance.
