Race-Oriented 48 Pitch Pinion for Consistent Drivetrain Performance

The 3Racing 48 Pitch Pinion Gear 49T is engineered for competitive and track-focused use. Machined from 7075 aluminium and finished with a hard coating, this component retains accurate tooth form under repeated high torque cycles.

Material Choice and Surface Treatment

Using 7075 aluminium gives a high strength to weight ratio while the hard coating enhances surface hardness to delay wear. These choices maintain engagement fidelity and reduce the need for frequent replacement in tuned setups.

Application and Tuning Considerations

Designed for 48 pitch gear trains, the pinion suits racers adjusting final drive ratios for lap time or acceleration. Ensure shaft fit and motor position are compatible to keep backlash predictable and to preserve consistent meshing under braking and acceleration loads.

Fitting Procedures for Optimal Mesh

Install the 3Racing 48 Pitch Pinion Gear with careful shimming to achieve the manufacturers recommended mesh. Verify alignment under load and recheck after the first few runs to confirm no movement has altered the engagement pattern.

Confirm your motor shaft diameter and set screw location; the pinion must match the shaft or use an appropriate adapter to ensure secure mounting.
Inspect tooth contact pattern on the spur, check for lateral movement and retorque set screws after a short running session to confirm stability.
Maintain correct mesh, avoid overloading ratios, and keep drivetrain seals clean to prevent abrasive wear on the coated surface.
