RWC Shock NB Kit 38mm Span

Our NEEDLE BEARING CONVERSION KITS are a new, better way of doing things. Our top quality hardened steel needle bearing take the place of the DU bushing. The needle bearing is matched with a hardened, polished inner ring (axle) that, when used with the supplied spacers, is a perfect fit between the rocker arms or frame mounts. When the shock hardware is tightened, the needle bearing axle is locked into place. No side loading is applied to the bearing or the shock body in any way. Sealed spacers center the shock and protect the bearing. This kit is for mounting spans of 38mm with 6mm or 8mm bolts.

Don’t be suckered into buying a cheap knock-off kit! Our kits are the original and include machined and anodized aluminum spacers with integrated seals. We include up to 4 different hardened bearing steel axles of varying Outside Diameters so that you get a custom fit regardless of slight variations in your shock eyelet bore. Shock bores typically run between 15.01mm and 15.03mm. As the needle bearing assembly gets pressed into the shock eyelet, the cup holding the rollers gets compressed, which affects the Inside Diameter of the bearing. These variations in bearing Inside Diameter require corresponding variations in axle Outside Diameter in order to have a proper fit. Too tight a fit results in binding, while too loose a fit results in excess play. With our kit, you are guaranteed a custom fit and optimum performance.

  • For shocks with 15mm eyelets (as measured with bushing removed. For 38mm mounting spans. Works with 6mm and 8mm mounting bolts.
