RWC Shock Needle Bearing Kit, 30.00mm

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.

    • Great bushing replacement
      I purchased this plus the 40mm NBK for a DHX2 equipped Capra MkII. There was a significant improvement in how smooth the compressions were on the bike after replacing both bushings with the needle bearings. The bike felt so much smoother through all of its travel. Chris was also helpful in discussing whether or not to get a NBK for both ends of the shock, but seeing wear on the through bolts I decided to replace both and very happy I did.

    • Happy with purchases.
      I have ordered assorted bearings, fork service parts and tools from RWC. Every product I have ordered I have been immensely satisfied with. The needle bearing/spacer kit is great to cut friction slightly over the crappy plastic bushing in Fox shocks. anodized spacers add a bit of bling over the factory plastic stuff. Bearing tools are top notch machined and work perfectly at a slightly less price than others. I'm only about 4 hrs away in Southern NM so all my orders are dispatched within sometimes minutes of order and arrive in a couple days. i wiil continue to order from RWC for all the above listed reasons. Keep up the good work.
