Make your drivetrain stronger on your v1 Traxxas X-Maxx monster truck by installing our Billet Machined Steel Spur Gears. Our spur gears are a bolt-on upgrade that replaces your stock spur gear (Traxxas OEM part #6449/6449x) with a thick, strong steel gear that alters your gear ratio for higher speeds. The spur gears are available in 50-tooth (#C27078), 46-tooth (#C27077), and stock 54-tooth (#C27079) sizes.

NOTE: Instructions for installation are not included; if you do not know how to install the part, please ask your local dealer for assistance. All products require some prep out of the package - some components are assembled for packaging purposes only, so we strongly recommend that you check all metal-to-metal fasteners for tightness, check fitment and adjust if needed, and use liquid threadlock where applicable. Failure to do so is not a warranty-related incident.

Extra hardware, shims, or spacers may be required for some installations. Some parts may require permanent modification to the vehicle for fitment, and may eliminate certain OEM features. Items that are different from `the OEM part (such as our snow & sand conversions, piggyback shocks, EXT suspension, or extended wheel hubs) may require modification to the vehicle for proper clearance. Some Integy-branded items may be only compatible with the vehicle's OEM parts but not with another Integy-branded item due to design limitations. For multiple-fitment items, some parts may not be used based on application.
