Designed for brushless and brushed motor upgrades in RC cars, the set comes with set screws and a hex key for simple installation. If you are fine-tuning your car's gearing for better speed or acceleration, this set offers a practical range of options.\u003c\/p\u003e\u003ch2\u003eWhat tooth counts are included in this pinion gear set?\u003c\/h2\u003e\u003cp\u003eThe set contains five gears: 16T, 17T, 18T, 19T, and 20T. All share the same 48 pitch (48DP), meaning the distance between teeth is consistent across the set. This pitch must match your spur gear's pitch for proper meshing.\u003c\/p\u003e\u003ch2\u003eGear specifications and dimensions\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePitch\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e48DP (48 teeth per inch of pitch diameter)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTooth counts\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e16, 17, 18, 19, 20 (one each)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eShaft hole diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3.175mm (1\/8 inch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHardened steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIncluded tools\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHex key (screwdriver) and set screws for each gear\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eHow to choose the right pinion gear for your RC car\u003c\/h2\u003e\u003cp\u003eStart with the smallest tooth count (16T) and test the car's performance at low speeds. Gradually move to larger pinions (17T-20T) while monitoring the temperature of the ESC and motor after each run. If the motor or ESC gets too hot, reduce the pinion size. This method helps you find the fastest gear without overheating the electronics.\u003c\/p\u003e\u003ch2\u003eInstallation and use tips\u003c\/h2\u003e\u003cp\u003eEnsure the motor shaft is clean and fully inserted into the gear's bore. Tighten the set screw firmly using the provided hex key. Always confirm that the pinion and spur gear have the same pitch (48P) or the teeth will not mesh properly. The included hex key works for all set screws in the set.\u003c\/p\u003e\u003ch2\u003eFrequently asked questions about this gear set\u003c\/h2\u003e\u003ch3\u003eAre these gears compatible with any RC motor?\u003c\/h3\u003e\u003cp\u003eThey fit motors with a 3.175mm (1\/8 inch) shaft diameter. Measure your motor shaft to confirm the size before purchase.\u003c\/p\u003e\u003ch3\u003eWhat does 48P mean?\u003c\/h3\u003e\u003cp\u003e48P refers to the diametral pitch: the number of teeth per inch of the gear's pitch diameter. This standard is common in 1\/10 scale and other RC cars.\u003c\/p\u003e\u003ch3\u003eCan I use these with a brushed motor?\u003c\/h3\u003e\u003cp\u003eYes.
