Durable 3Racing pinion for consistent gear mesh

The 3Racing 64 Pitch Pinion Gear 21T is built for hobbyists wanting a reliable, light pinion that resists wear. Its 7075 aluminium core and hard coat finish combine to offer strength without adding unnecessary weight.

Performance notes for the 21T

The 64 pitch profile delivers predictable engagement and is well suited to setups focused on reachable top speed and steady torque delivery. It is a practical choice for many 1/10 scale applications.

Fitting checklist

Ensure correct axial position and tighten the grub screw to the recommended torque. Verify mesh under load before full runs to prevent premature tooth damage and to get quiet operation.

The 3Racing 21T pinion fits many 1/10 off-road platforms that use 64 pitch gearing; check your spur specifications to confirm compatibility.
7075 aluminium with a hard coating offers a good balance of lightness and wear resistance; it may show wear differently from steel but performs very well when mesh and lubrication are correct.
Swapping pinion sizes is straightforward but remember to recheck gear mesh and motor clearance each time to avoid binding or tooth damage.
