Made from hardened steel, they are intended for use with steel spur gears only. Ideal for upgrading or tuning the speed of Arrma Typhon, Kraton, Outcast 6s and similar 1\/8 or 1\/10 RC vehicles that use Mod 1 spur gears and a 5mm motor shaft.\u003c\/p\u003e\u003ch2\u003eWhy the Material and Compatibility Matter\u003c\/h2\u003e\u003cp\u003eThese pinion gears are constructed from hardened steel, a material chosen for its durability and resistance to wear under high loads. However, the manufacturer explicitly warns against assembling them with plastic or aluminum spur gears. Doing so can quickly damage or destroy your spur gear because the hardened steel teeth are much harder than those softer materials. For best results and longevity, pair these pinions with a steel spur gear of the same Mod 1 pitch.\u003c\/p\u003e\u003ch2\u003eWhich Teeth Count for Your Setup?\u003c\/h2\u003e\u003cp\u003eThe set provides five different tooth counts: 15T, 16T, 17T, 18T, and 19T. Changing the pinion gear is one of the easiest ways to adjust your RC car’s speed and acceleration. A lower tooth count (like 15T) gives more torque and quicker acceleration, while a higher tooth count (like 19T) increases top speed. Having five options lets you fine-tune your vehicle for different tracks, terrain, or driving styles without buying individual gears.\u003c\/p\u003e\u003ch2\u003ePinion Gear Measurements at a Glance\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePitch\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMod 1 (Module 1)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInner Diameter (bore)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTeeth Options\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e15, 16, 17, 18, 19\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\u003eSet Includes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5 pinion gears, 5 grub screws, 1 steel hex key\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat Buyers Often Ask\u003c\/h2\u003e\u003ch3\u003eCan I use these pinion gears with plastic or aluminum spur gears?\u003c\/h3\u003e\u003cp\u003eNo. Because these are hardened steel, they should only be used with steel spur gears.
