Many people have complained of breaking rear hub carriers and until now there was no solution to an unbreakable hub carrier. RC4WD is the first and only company to tackle such a complicated part and until now you could not buy these separately. You can now buy the rear hub carrier set as a separate item. You will get two sets, a right and a left. Each hub carrier is beautifully 3D machined and includes all 3 pieces to make a complete rock solid and bash proof hub carrier. Inventory is limited so let your dealers know you want these so they order now.
