This kit is designed for 8mm shock hardware.  To make it compatible with 6mm bolts, please add this item to your cart: 8 x 6mm Reducing Sleeve Our NEEDLE BEARING CONVERSION KITS are a new, better way of doing things. Our top quality hardened steel needle bearing takes 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. Until your shock is riding on bearings, you will never take advantage of its true capabilities.

The breakthrough performance and popularity of our needle bearing kits has inspired some cheap knock-off kits. Only our kits include:
-Machined and anodized aluminum spacers with integrated seals.
-Up to 4 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.
