48P Pinion Gear Set 28T-32T (5 Gears) for 1/10 RC Cars – Hardened Steel, 3.175mm Shaft
48P Pinion Gear Set 28T-32T (5 Gears) for 1/10 RC Cars – Hardened Steel, 3.175mm Shaft
This pinion gear set includes five 48-pitch hardened steel gears with tooth counts from 28 to 32, designed for motors with a 3.175mm shaft. Perfect for 1/10 scale RC cars, trucks, and buggies, it lets you fine‑tune your gear ratio for more speed or more torque. The set comes with mounting hardware and a hex wrench for straightforward installation.
Why Five Different Tooth Counts?
Having 28T, 29T, 30T, 31T, and 32T gears means you can easily change your RC car’s performance. A smaller pinion (e.g., 28T) gives higher acceleration and torque, while a larger one (32T) increases top speed. Swap gears depending on your track or terrain without buying separate sets.
Built to Last in High‑Performance Models
Each gear is made from hardened steel, which resists wear under the stress of fast, powerful 1/10 scale vehicles. The 48 pitch (48P) ensures smooth meshing with common spur gears, and the 10mm gear height fits standard motor shafts.
What You Need to Know About Fit
These gears are designed specifically for motors with a 3.175mm shaft diameter (common in 540‑size motors). They work with 1/10 scale RC cars, monster trucks, and buggies that use 48P spur gears. Always confirm your spur gear pitch and motor shaft size before ordering.

Frequently Asked Questions
How do I choose which tooth count to use?
Use the smallest gear (28T) for quicker acceleration and climbing; use the largest (32T) for higher top speed on flat surfaces. The best choice depends on your vehicle, motor, and driving conditions. Try different ones to match your setup.
What's the correct way to install these pinion gears?
Loosen your motor slightly to slide the pinion onto the motor shaft. Make sure the set screw sits on the flat part of the shaft. Re‑tighten the motor, leaving a gap of about the thickness of a sheet of paper between the pinion and spur gear.
Will these work with my 1/10 scale RC car?
They fit any 1/10 scale model that uses a 3.175mm motor shaft and 48P spur gear. Common platforms include Traxxas, Redcat, and many other brands. Double‑check your spur gear pitch before buying.
What's included in the package?
You get five pinion gears (28T, 29T, 30T, 31T, 32T), five M3 grub screws, and one hex wrench. Everything needed for installation.
