Step Up to Even Greater Off-Road Capability
Boost your TRX-4M's off-road performance even further by adding the optional portal axle kit for increased center ground clearance and a wider track. Standard TRX-4M trucks can also upgrade to the taller 2.4″ Mickey Thompson Baja Pro XS tires found on High Trail edition trucks for even more ground clearance and a more aggressive stance.
