Spur Gear 48P - 81T

The Arrowmax Spur Gear 48P – 81T (SCH-AM348081) is a straightforward replacement or ratio-tuning option for RC models that run 48‑pitch gearing. The 81‑tooth count helps fine‑tune the final drive ratio for smooth, consistent power delivery across a variety of track layouts.

Suggested compatibility: vehicles that use 48‑pitch spur gears and can accommodate an 81‑tooth size. Please confirm fitment against your model’s manual, checking spur mounting pattern, gear cover clearance and mesh range.

Pair this spur with an appropriate 48‑pitch pinion to hit your target rollout. Set mesh and backlash carefully to minimise wear and keep the drivetrain quiet and efficient.
