The included coupler also allows fitment on vehicles with 5mm or 3.175mm pinion shaft apertures, making it adaptable to a range of compatible RC platforms.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between the 11T and 15T gear options?\u003c\/h4\u003e\n\u003cp\u003eA: The tooth count affects your gear ratio. An 11T (11-tooth) pinion gear provides more torque and is better for off-road or climbing applications, while a 15T (15-tooth) pinion gear delivers higher top speed — ideal for flat track racing. Choose based on your driving style and terrain.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Are these gears better than the stock plastic gears?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. Unlike standard plastic or ABS gears that can strip under stress, these hardened steel gears are engineered for high-strength performance and long service life, reducing the frequency of replacements and keeping your RC car running smoothly.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Do I need any special tools to install this gear set?\u003c\/h4\u003e\n\u003cp\u003eA: Basic RC maintenance tools such as a small screwdriver or hex wrench set are typically sufficient.
