X-Factory X-6 and B4 front axles
X Factory have announced new front axles to fit both the X-6 Squared and the RC10B4. B4s are sold with steel front trailing axles that secure the wheel with a nut. The nut protrudes from the front wheel and can catch on things. The new X Factory trailing front axles are hardened steel so they won’t break and secure the wheel with a button head screw. Made for X Factory by M.I.P., the new axles are completely drilled through the center so they each weigh just 1 gram more than the aluminum FT axle. The package contains two axles and four button head screws, X Factory’s axles are secured in the car with a screw instead of an E-clip, so each pack contains everything needed for both sides of the car.
