Product Details
The Revolver 3 bolt rear brake hub carries your brake rotor on the rear axle of an outlaw kart or go kart. It is machined from 7075 aluminum, bored at 1.25 in to drop straight onto a standard rear axle, and priced to compete with the plain hubs it replaces.
At almost 10 g lighter than other brake hubs, it takes weight off the fastest-spinning part of the kart, and 7075 is stiff enough to keep the rotor running true under hard braking instead of flexing and cooking pads. It looks a lot better than a stock hub while it does it.
Choose it bare, or paired with our titanium bolt kit, which includes the pinch bolt and three rotor bolts drilled and ready to be safety wired. If titanium is not your thing, the steel option gives you drilled steel rotor bolts with a non-drilled steel pinch bolt.
