Designed for 1\/10 scale RC cars, boats, and planes, each gear is machined from hardened steel to handle high-torque loads. The set also includes five grub screws and a steel hex key for installation.\u003c\/p\u003e\n\n\u003ch2\u003eWhy must these pinion gears only be used with steel spur gears?\u003c\/h2\u003e\n\u003cp\u003eThe hardened steel construction of these pinions is much harder than plastic or aluminum. Running them against a softer spur gear will quickly wear down or chip the spur gear teeth, leading to poor mesh and eventual failure. For best performance and longevity, pair these 48-pitch pinions with a steel spur gear of the same pitch.\u003c\/p\u003e\n\n\u003ch2\u003eWhich RC vehicles are compatible with these pinions?\u003c\/h2\u003e\n\u003cp\u003eThese gears fit any RC car, boat, or plane that uses a 48-pitch spur gear and a motor shaft diameter of 3.175mm (1\/8 inch). They are especially common in 1\/10 scale touring cars, buggies, and short-course trucks. Before ordering, confirm your spur gear’s pitch (must be 48P) and shaft size.\u003c\/p\u003e\n\n\u003ch2\u003eGear set details at a glance\u003c\/h2\u003e\n\u003ctable\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\u003ePitch\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e48P (48 teeth per inch)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBore 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\u003eTeeth counts included\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e22T, 23T, 24T, 25T, 26T\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eQuantity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5 pinions + 5 grub screws + 1 hex key\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use these with plastic or aluminum spur gears?\u003c\/strong\u003e\u003cbr\u003eNo. The manufacturer explicitly warns against it because the hardened steel pinions will damage softer spur gears.
