Always verify your specific model's part number before ordering to ensure correct fitment.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between the tooth counts (17T, 21T, 26T, 29T, 64T)?\u003c\/h4\u003e\n\u003cp\u003eA: The tooth count determines the gear ratio between the motor pinion and the spur gear. A higher tooth count on the spur gear (e.g. 64T) paired with a smaller pinion results in more torque and slower top speed, while a lower tooth count provides higher top speed suited to racing on smooth tracks. Choosing the right combination lets you optimise your RC car's performance for your driving style.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Why choose steel gears over plastic gears for my HSP RC car?\u003c\/h4\u003e\n\u003cp\u003eA: Steel gears are significantly more durable than plastic alternatives. They resist stripping under high torque, handle heat better during extended run sessions, and last much longer — making them a smart upgrade for anyone who bashes hard or runs a high-power motor setup.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is installation straightforward for these replacement gears?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. These gears are designed as direct-fit replacements for compatible HSP models. Basic RC car maintenance tools and a copy of your vehicle's manual are all that's needed for a straightforward swap.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Which HSP RC car models are compatible with this spur differential main gear set?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This steel spur differential main gear and pinion set is designed for HSP 1:10 scale RC vehicles, including popular HSP buggies, truggies, touring cars, and off-road models.
