Why Upgrade to Steel?
Stock plastic gears in RC cars can strip under high torque or aggressive driving. Swapping to a steel spur and pinion gear dramatically improves durability, especially for bashing, racing, or high-power motor setups. This set is a favourite among RC hobbyists looking for a reliable, cost-effective upgrade that keeps their car on the track longer.

Frequently Asked Questions
Q: Which HSP RC car models are compatible with this spur differential main gear set?
A: 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. Always verify your specific model's part number before ordering to ensure correct fitment.
Q: What is the difference between the tooth counts (17T, 21T, 26T, 29T, 64T)?
A: 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.
Q: Why choose steel gears over plastic gears for my HSP RC car?
A: 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.
Q: Is installation straightforward for these replacement gears?
A: 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.
