Gabriel Bairdon Traxxas TRX-4M Low Range Transmission Gear Set (Crawl) (11T)

Perfect if you get a higher rpm aftermarket motor. Provides incredible power but will strip out with too much torque.

I did two stars because Traxxas doesn't offer a metal gear other places do found that out afterwards but they work great until they stripped out I knew they would

This really helps the 4m crawl better. If your doing indoor courses its a must

Works great, can’t complain with the stock motor setup

What reviewers say

Reviewers largely agree the low range gear set improves crawling performance on the TRX-4M, with praise for its benefit on indoor courses and with the stock motor. Opinions diverge on durability: one reviewer found the gears strip under high torque, particularly with a higher-rpm aftermarket motor, and another reported stripping after a period of use. One reviewer could not get the set to fit or work in a stock transmission. The gears are plastic, and one reviewer noted Traxxas does not offer a metal option. All reviews refer to the 11T variant.

  • + Improves crawling performance
  • + Good for indoor courses
  • + Works well with stock motor
  • − Gears can strip under high torque
  • − Plastic gears, no metal option
  • − Reported fit problem in one stock transmission
