Exotek introduces alloy rear hubs with vertical ball stud mounting for the HB D413. These heavy duty rear hubs are machined from 7075 aluminium to be lightweight and they are machined a second time to insure precise bearing fit and polished and anodized in factory orange. They have a conventional upright ball design for precise and easy roll center adjustments. Allows an optional 3mm set screw (not included) on the hinge pin for improved hinge pin fit. Includes (2) 2mm alloy spacers to match the stock geometry. Requires D413 6mm ball stud (112727) and D413 ball cups (112724).
