Frequently Asked Questions

Q: What RC car models are compatible with the U13F Hardened Steel Gear Set?

A: This gear set is specifically designed for U13F remote control car and truck models. 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.

Q: What is the difference between the 11T and 15T gear options?

A: 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.

Q: Are these gears better than the stock plastic gears?

A: 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.

Q: Do I need any special tools to install this gear set?

A: Basic RC maintenance tools such as a small screwdriver or hex wrench set are typically sufficient. No advanced modifications are required — this is a straightforward drop-in upgrade for compatible U13F models.
