50mm Kart Axle Key – Precision Machined Keyway for OTK, Parolin & KR 50mm Axles
About this part
High-quality axle key for 50 mm kart axles, sold individually. Precision machined for a secure, reliable fit in the axle keyway, so sprocket hubs, brake disc carriers and wheel hubs stay locked to the axle under acceleration and braking.
Fitment
- Axle: 50 mm
- Compatible with OTK (Tony Kart, Kosmic, Exprit), Parolin and KR karts using 50 mm axles
- Use for sprocket hub, brake disc and wheel hub mounting
Quantity
- Price is per key.
Why keep spares
Axle keys are small, easy to lose during an axle swap and easy to round off if a hub was run loose. A worn key lets the hub rock on the axle and shows up as a clunk on throttle. Keep a few in the kart bag.
Pairs with our 50 mm quick-change sprocket hub and axle bearings. Stocked in California.
