A New Level of Off-Road Capability

Just like the larger TRX-4, new TRX-4M portal axles increase your off-roadcapability by raising the vehicle at the axles. centre ground clearance increases byover 10 mm and the track widens by 9 mm for a whole new level of 1:18 scale crawlingcapability.

For optional 2-speed high/low transmission - Use the included bluegears to maintain stock vehicle speed in high gear and crawling speed in low gear.

Step Up to Even Greater Off-Road Capability

To boost your TRX-4M's performance even further add the optional two-speed transmission to maintain stock speed in high gear and provide an ultra-low crawl gear for maximum rock-crawling torque. Standard TRX-4M trucks can also upgrade to the taller 2.4" Mickey Thompson Baja Pro XS tyres found on High Trail edition trucks for even higher ground clearance and a more aggressive stance.
