Threaded Dust Cap

Ingenious new design, another first in the industry by Hyper Racing. The Threaded Dust Cap for HBS Wheel Centers will thread into the wheel center with an o-ring seal to keep water and dirt out to protect bearing. The flats machined into the front of the cap allows our 25-540 wrench to be used to tighten and loosen the cap. No more hammers, missing caps after racing, destroyed o-rings, and scratched wheel centers.
