65T Steel Main Gear SEMX2065T Precision Upgrade for TRAXXAS E-MAXX by GPM  [SEMX2065T]

Precision 65T main gear for TRAXXAS E-MAXX applications

This single-piece 65-tooth steel main gear is engineered as an aftermarket replacement for TRAXXAS E-MAXX gearboxes, offering enhanced toughness and consistent tooth geometry for improved durability in tuned drivetrains. The component is finished to tight tolerances to preserve correct centre spacing and mesh characteristics when fitted into standard E-MAXX gearcases.

Installation follows standard gearbox service procedures: remove the cover, extract the existing spur assembly, locate the SEMX2065T onto the drive shaft while ensuring correct pinion engagement, then reassemble with original spacers and fasteners. Perform manual rotation checks to confirm smooth engagement prior to dynamic testing.

Using a steel main gear modifies contact stress distribution and increases load capacity compared to plastic spurs. For optimal service life, verify pinion hardness, inspect bearings for axial play, and confirm backlash is within acceptable limits after fitment.

Specified for repair and performance-oriented builds on TRAXXAS E-MAXX models, SEMX2065T delivers consistent mesh and higher wear resistance when paired with appropriately matched pinions and bearings.
