LEESPEED 48 Pitch Titanium Pinion Gear 39T LS-TP-48039
Couldn't load pickup availability
The LEESPEED 48 Pitch Titanium Pinion Gear 39T is a lightweight, performance-focused gearing option for RC racers and enthusiasts fine-tuning their drivetrain setup. Designed for use with compatible 48-pitch spur gears, this 39-tooth pinion provides a taller gearing option that can increase potential top speed when matched correctly to your motor, ESC and vehicle setup.
Its titanium construction offers a strong, low-mass solution for competitive RC applications where efficient rotating mass and precise gearing matter. The 39T size is particularly suited to setups requiring higher overall gearing, but motor temperature and drivetrain load should always be monitored after making gearing changes.

FAQ
What does 48 pitch mean? 48 pitch refers to the tooth size and spacing used by the gear. This pinion must be paired with a compatible 48-pitch spur gear for correct mesh.
What effect will a 39T pinion have on my RC car? Compared with a smaller pinion on the same spur gear, a 39T pinion creates taller gearing. This generally increases potential top speed while also increasing load on the motor and ESC.
Will this fit my motor? Fitment depends on the motor shaft diameter as well as the available adjustment range in your motor mount. The published LEESPEED listing confirms the 48P and 39T specifications but does not state the bore diameter, so confirm shaft compatibility before installation.
Can I use this with a 0.6 Module spur gear? No. 48 Pitch and 0.6 Module are different gear standards and should not be mixed. Both the pinion and spur gear must use the same pitch or module.
Will a larger pinion always make my vehicle faster? Not necessarily. Taller gearing can increase theoretical top speed, but excessive gearing can cause high motor temperatures, reduced acceleration and increased ESC load. The best ratio depends on the motor, vehicle weight, track and driving conditions.
How do I know if my gearing is too tall? Check motor and ESC temperatures regularly after installing the new pinion. Excessive heat, sluggish acceleration or thermal shutdown can indicate that the gearing is too aggressive for the setup.
Important Notes
- Confirmed manufacturer part number: LS-TP-48039.
- Requires a compatible 48-pitch spur gear.
- Bore diameter is not stated in the available manufacturer/retailer information; confirm motor shaft compatibility before purchase.
- Do not mix 48P gears with 0.6 Module, 32P, 64P or other incompatible gear standards.
- A 39T pinion may require significant motor-mount adjustment and may not physically fit every chassis.
- Set correct gear mesh before operating the vehicle.
- Monitor motor and ESC temperatures whenever changing gearing.
- Ensure the pinion is securely fastened before running the vehicle.
- Motor, spur gear and vehicle are not included.
