Engineered for Victory. Born from Competition. The RRP FSX Rear Hub Set is the next evolution of our proven RxMOD rear hubs, developed with direct input from Team Rubrix drivers and their race-proven experience. Machined from 7075 aluminum, the FSX hubs are offered in both 2° of built-in toe-in and 1° of built-in toe-in and now support 6x12x4mm bearings for improved reliability, smoothness, and drivetrain performance. The updated design also incorporates grub screws for both upper and lower 3mm hinge pin locations, providing secure and precise suspension setup.
