Performance Spur for Inferno MP10

The Kyosho IFW639-58S lightweight 58-tooth spur is tailored for the Inferno MP10 chassis. Its 0.8 module pitch gives finer tooth spacing than the 1.0 module, which helps with smoother acceleration and steadier power delivery in race conditions.

Precise Gearing for Competitive Use

Fitting this spur allows more granular selection of final drive ratios so you can match performance to different tracks. The refined tooth form improves engagement consistency under load.

Compatible Components Required

To use this spur you must source the matching lightweight one-piece clutch bells separately: No.97058LW-16 (0.8M/16T) or No.97058LW-17 (0.8M/17T). These parts are essential to achieve the correct 0.8M mesh.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this change my car's top speed?

Top speed depends on the pinion you pair with this 58T spur; the spur itself allows finer steps so you can tune for either acceleration or top end.

Are the No.97058LW clutch bells mandatory?

Yes, use the No.97058LW-16 or No.97058LW-17 bells to match the 0.8M tooth pitch; they keep correct engagement and reduce the risk of uneven wear.

How often should I inspect the spur?

Check the spur teeth during regular maintenance intervals and after any heavy impact; ensure mesh has not opened up and that no teeth show abnormal wear.
