Tech Tip: Addressing a precise fit into the hub bore

For accurate balancing, the hub bore of a wheel must be properly centered on the balancer shaft. On many modern wheel designs, traditional cones can center poorly due to their high-taper design and can fit improperly within the hub bore by bottoming out.

Hunter Engineering offers Direct-Fit Collets which feature a shorter, low-taper design that fits precisely into the hub bore only. This design promotes accurate centering while protecting against damage to certain designs like plastic clad wheels.
