A 3.175mm coupler is included to adapt these pinions for motors with 3.175mm shafts. Each pinion features an M4 set screw to secure it to the shaft. This set is suitable for RC buggies and monster trucks that use 5mm or 3.175mm motor shafts.\u003c\/p\u003e\u003ch2\u003eWhat motor shaft sizes are compatible?\u003c\/h2\u003e\u003cp\u003eThe pinions have a 5mm inner diameter bore, designed to fit 5mm motor shafts directly. Additionally, the included coupler reduces the bore to 3.175mm, allowing use with common 3.175mm shaft motors. This makes the set versatile for different motor types.\u003c\/p\u003e\u003ch2\u003eGear ratio flexibility with four tooth counts\u003c\/h2\u003e\u003cp\u003eThe set includes four pinions with 14, 16, 18, and 20 teeth. By swapping pinions, you can change the gear ratio of your RC vehicle. A lower tooth count (14T) typically provides more acceleration, while a higher count (20T) can increase top speed. Having these options allows you to fine-tune performance based on your track or driving style.\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTooth Pitch\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e32\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\u003eBore Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5.0mm (0.196 inch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTooth Counts\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e14T, 16T, 18T, 20T\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSet Screw Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eM4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIncluded\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4 pinions, 1 coupler, 1 allen key\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eBuild quality and construction details\u003c\/h2\u003e\u003cp\u003eEach pinion is made from high-strength hardened steel for increased wear resistance.
