Setup Notes

The 92mm hub is the standard starting point for most OTK chassis setup. It sits in the middle of the rear hub range, offering a balanced rear-end response across a broad range of track conditions and engine classes. A longer hub increases axle rigidity at the rear wheel, which can add rear grip and stability under braking and acceleration. Compare with the 77mm short hub, 115mm long hub, and 148mm extra long hub when setting up your chassis.

Designed for use with the OTK 50mm Rear Axle. Wheel nuts, axle, axle key, and fixing hardware are sold separately.
