A new level of off-road capability. Just like the larger TRX-4, the new TRX-4M portal axles increase your off-road capability by raising the vehicle at the axles. Center ground clearance increases by over 10 mm and the track widens by 9 mm for a whole new level of 1/18 scale crawling capability.

The kit includes all-metal portal gears with self-lubricating bushings for long-lasting performance. The axles come completely assembled and ready to install with updated transmission gears to maintain stock speed and torque. Portal axles are also compatible with most TRX-4M accessories and work great with the optional two-speed transmission.

For standard single-speed transmission, use the included red gears with the single-speed transmission for general use or keep the standard gearing for crawling purposes. Portal axles are not compatible with low-range gears.

For optional two-speed high/low transmission, use the included blue gears 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-inch Mickey Thompson Baja Pro XS tires found on High Trail edition trucks for even higher ground clearance and a more aggressive stance.
