Upgrade XB Series drivetrains with XRAY 365781

Hobbyists wanting a stronger, lighter spur gear will appreciate the XRAY 365781 Composite Slipper Clutch Spur Gear 81T. Built from a tailored composite, this gear balances toughness and low mass to stand up to high RPM brushless motors while helping keep rotating weight down. Precision molding reduces wear points so the gear runs smoothly under race conditions.

Main specs and race-oriented benefits

  • Material: Custom composite formula for improved durability and weight savings.
  • Tooth Count: 81T, marked for quick verification during maintenance.
  • Compatibility: Suited to older XB series models when replacing or upgrading the slipper clutch gear.
  • Performance: Designed to resist wear during sustained high-speed runs.
Remark :
Due to limited stock availability, please notice that some XRAY 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 81T gear work with my XB slipper clutch assembly?

Check your XB series model's parts list for spur gear size and slipper hub fitment. This XRAY 365781 is made for older XB slipper setups but confirm hub thickness and spline match before fitting.

How should I set gear mesh with a composite spur?

Start with a slight clearance at the crown of the pinion, then tighten to a snug mesh under light load. Recheck after a few runs since composite can seat in differently than metal gears.

What maintenance helps extend gear life?

Keep the spur clean of debris, ensure correct slipper tension to avoid excess slip, and inspect teeth regularly for chipping when running powerful brushless motors.
