Exotek Racing - XB4 Rear Hubs V2, 7075Heavy duty 7075 alloy machined rear hub set for the XB4 '18 and '17 series buggies. Symmetrical design means our hubs can be used on either the left or right side making for easier front or rear shock mounting on the arms. These hubs are also narrowed by 2mm compared to the stock hubs thus allowing more wheelbase adjustments with the included alloy shims. Also includes 2mm roll center shims to match the stock geometry.
