The Traxxas TRX-4M Brushless Power System 6250 is a plug-and-play upgrade designed to deliver more speed, stronger crawling torque and smoother low-speed control for TRX-4M models. With up to 50% more speed than brushed setups, this fully waterproof brushless system is ideal for monster trucks, High Trail rigs and technical mini crawler builds.

The 3350Kv brushless outrunner motor provides excellent torque and precision, while the waterproof 3-channel brushless ECM retains standard TRX-4M features, including Pro Scale lighting control. Field Oriented Control delivers smooth throttle response for crawling, trail driving and high-speed fun.

Compatible with 2S LiPo power and both TQ and TQi transmitters, the TRX-4M Brushless Power System uses the same footprint and mounting points for true plug-and-play installation — no modifications required. It works with all existing TRX-4M parts and accessories, including Pro Scale LED light kits and the high/low two-speed transmission.
