CRAFT WERKS BAJA HUB NUTZHere is the latest From CraftWerks-RC.... Our Hub Nutz fit both the 5B and 5T and are made from 303 Stainless Steel for strength and corrosion resistance. The plastic rear hubs tend to crack and break around the rear hub/bearing carrier due to stress when under hard driving conditions. When this happens it can affect your handling, break or damage your drive cups and axles, etc. The CraftWerks-RC Hub Nutz offer more than 50% more surface area than the stock 4mm nylon lock nut for improved strength that will eliminate the flex, breakage and strengthen up your rear hubs. Includes 8 CraftWerks-RC Hub Nutz, enough for one complete Baja. No modifications are needed, Simply remove your existing 4mm hub/bearing carrier nuts and reinstall using the CraftWerks-RC Hub Nutz.
