Improve the crawling characteristics of your Traxxas TRX-4 with this overdrive ring and pinion gear set from Treal Hobby. Designed for all TRX-4 models, this gear set creates an overdrive ratio directly through the ring and pinion gears instead of the portal box. The revised gearing can help improve front-end wheel speed and make it easier to maintain momentum through technical terrain. It is a practical drivetrain upgrade for drivers looking to fine-tune their TRX-4 crawling setup.
