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.\u003c\/p\u003e\n\u003cp\u003eIts 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.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine LEESPEED RC pinion gear\u003c\/li\u003e\n\u003cli\u003e39-tooth configuration\u003c\/li\u003e\n\u003cli\u003e48-pitch gear profile\u003c\/li\u003e\n\u003cli\u003eTitanium construction\u003c\/li\u003e\n\u003cli\u003eLightweight performance-oriented design\u003c\/li\u003e\n\u003cli\u003eDesigned for compatible 48P spur gears\u003c\/li\u003e\n\u003cli\u003eIdeal for fine-tuning acceleration and top speed\u003c\/li\u003e\n\u003cli\u003eSuitable for performance and competition RC applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: LEESPEED\u003c\/li\u003e\n\u003cli\u003eManufacturer Part Number: LS-TP-48039\u003c\/li\u003e\n\u003cli\u003eProduct Type: RC Motor Pinion Gear\u003c\/li\u003e\n\u003cli\u003eGear Pitch: 48 Pitch \/ 48P\u003c\/li\u003e\n\u003cli\u003eTooth Count: 39T\u003c\/li\u003e\n\u003cli\u003eMaterial: Titanium\u003c\/li\u003e\n\u003cli\u003eApplication: RC Drivetrain Gearing\u003c\/li\u003e\n\u003cli\u003eBore \/ Motor Shaft Size: Not Specified\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIncludes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 × LEESPEED 48 Pitch Titanium Pinion Gear 39T\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does 48 pitch mean?\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat effect will a 39T pinion have on my RC car?\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this fit my motor?\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this with a 0.6 Module spur gear?\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill a larger pinion always make my vehicle faster?\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I know if my gearing is too tall?\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eConfirmed manufacturer part number: LS-TP-48039.\u003c\/li\u003e\n\u003cli\u003eRequires a compatible 48-pitch spur gear.\u003c\/li\u003e\n\u003cli\u003eBore diameter is not stated in the available manufacturer\/retailer information; confirm motor shaft compatibility before purchase.\u003c\/li\u003e\n\u003cli\u003eDo not mix 48P gears with 0.6 Module, 32P, 64P or other incompatible gear standards.\u003c\/li\u003e\n\u003cli\u003eA 39T pinion may require significant motor-mount adjustment and may not physically fit every chassis.\u003c\/li\u003e\n\u003cli\u003eSet correct gear mesh before operating the vehicle.\u003c\/li\u003e\n\u003cli\u003eMonitor motor and ESC temperatures whenever changing gearing.\u003c\/li\u003e\n\u003cli\u003eEnsure the pinion is securely fastened before running the vehicle.\u003c\/li\u003e\n\u003cli\u003eMotor, spur gear and vehicle are not included.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OZRC","offers":[{"title":"Default Title","offer_id":52738239201592,"sku":"LS-TP-48039","price":21.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2849\/9768\/files\/LEESPEED_48_Pitch_Titanium_Pinion_Gear_39T_LS-TP-48039_1265f0d7-870e-41f5-891d-5a55e7a9340d.png?v=1785824767","url":"https:\/\/ozrc.com.au\/products\/leespeed-48-pitch-titanium-pinion-gear-39t-ls-tp-48039","provider":"OZRC","version":"1.0","type":"link"}
