3RACING 3RAC-PG6440 64 Pitch 40T Hard Coated Pinion Upgrade  [3RAC-PG6440]

Performance-Focused 3RACING 3RAC-PG6440 40T Pinion

The 3RACING 64 Pitch Pinion Gear 40T is aimed at builders who want dependable gearing with lower mass. Constructed from 7075 aluminum and treated with a hard coating, this pinion is made to endure repeated running without rapid surface wear.

Consistent Meshing for Better Control

Using a 64 pitch tooth profile helps achieve tighter engagement and steadier torque transfer. The 40-tooth size allows precise steps in gearing to tune acceleration and top speed for different track conditions.

Material Choice and Surface Finish

7075 aluminum is chosen to keep rotating mass down while offering solid load-bearing capability. The hard coating adds a protective layer to reduce abrasion on tooth flanks during routine use.

Easy to Fit, Wide Compatibility

Meant for many common 1/10 scale setups that accept 64 pitch pinions, installation follows standard pinion alignment and mesh checking procedures so you can fit it quickly at the bench.
