9843R Portal kit, complete (2.56:1 reduction) for the TRX-4m

A New Level of Off-Road Capability
Just like the larger TRX-4, new TRX-4Mportal 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 optional98912-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 9776R low-range gears.

For optional 2-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 Mickey ThompsonBaja Pro XStires found on High Trailedition trucks for even higher ground clearance and a more aggressive stance.
