Exotek Racing introduce this 0 degree rear hub set for 1/10th Team Associated off-road vehicles such as the B4, B4.1, B44, T4, T4.1, and SC10. They feature vertical style ball end mounting positions for variable roll center adjustments. Simply add shims under the ball ends to lower or raise the roll center. Three position ball locations match the Factory Team hubs for easy set up reference. They are CNC-machined from high-quality aluminium and make use of the same heavy duty oversized outer bearings, crush sleeve and shims as the factory team hubs. The simple design results in 30 percent lighter weight then the Factory Team hubs.
