Cobra Racing Traxxas X-Maxx / XRT 46T (M1.0) Hardened Steel Spur Gear Assembly

Upgrade the drivetrain on your Traxxas X-Maxx or XRT with a hardened steel spur gear built for serious 8S power, hard launches, heavy tires, and real bashing abuse. This is a direct replacement-style performance upgrade for drivers who want stronger gear engagement, better durability, and a more dependable setup than standard plastic or softer factory-style spur gears.

Why Upgrade?

The spur gear is one of the most important parts in your RC truck’s driveline. It transfers power from the motor pinion into the drivetrain, so when you add bigger tires, more throttle, harder landings, or aggressive gearing, the stock setup can become a weak point.

This hardened steel spur gear is built to handle more stress, more heat, and more abuse. It is ideal for bashers, speed runners, and high-power X-Maxx / XRT builds that need a tougher gear setup.

Other Gear Options

1. 50T M1.0 – Great all-around upgrade for X-Maxx / XRT setups using Mod 1.0 gearing.
2. 35T M1.5 – Great all-around upgrade for X-Maxx / XRT setups using Mod 1.0 gearing.

Make sure your pinion gear matches the spur pitch. M1.0 spur gears must be used with M1.0 pinions. M1.5 spur gears must be used with M1.5 pinions.
