This billet aluminum rear wheel hub slides onto a 40mm kart axle and bolts your wheel on with the three included 8mm studs. The 8mm keyway transfers torque cleanly while the short hub design cuts unsprung weight and gives extra clearance on tight sprint chassis. Perfect for LO206 sprint racing, the hub keeps wheels secure and aligned lap after lap whether you are new to karting or chasing tenths at the track.

Racers like the precise fit and Birel Red Army endorsement for LO206 sprint classes. The black anodized finish resists corrosion and looks clean next to any wheel package.

Will this 40mm x 50mm rear wheel hub fit my LO206 sprint kart?
Yes, it is designed specifically for 40mm axles with an 8mm keyway and is endorsed for LO206 sprint racing on common sprint chassis.
How do I install the hub and are the wheel nuts included?
Slide the hub onto the axle, align the key, tighten the set screw, then bolt your wheel on using the pressed-in 8mm studs. Wheel nuts are not included and must be purchased separately.
