9843R PORTAL AXLE KIT TRX4M
-
Detail
A New Level of Off-Road Capability
Just like the larger TRX-4®, 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 9891 2-speed transmission.

Works great, no issues, super durable. Only reason I’m not giving 5 stars? The packaging was torn on arrival. Inside was fine, but felt like it survived a bar fight. Maybe beef up the box next time?

Works well, but had a slight misalignment during setup. Needed minor tweaking. Not a dealbreaker, just took extra time. Performance is good once dialed in.

I’m not a mechanic, but this kit made me feel like one. Bolted right in, zero issues after two muddy weekends. My TRX4M now laughs at obstacles that used to stop me. If you’re hesitating—don’t.

Not gonna lie, I bought this for the cool factor... but now I’m obsessed with how well it performs. Mud, gravel, steep hills – this thing laughs at terrain. Also got compliments from a guy named ‘Bubba’ at the off-road park. That’s a win in my book.

Works well enough, but had a slight binding issue out of the box. Took some adjustment to get smooth rotation. Once dialed in, performance improved a lot. It’s good, just not plug-and-play perfect.
Haz*******idt
I’m not the most experienced builder, but the kit came with clear alignment markers and everything fit perfectly. Ran it through mud, rocks, and creek beds—no issues at all. This is what aftermarket done right feels like. Highly recommend.
Tho******son
Solid kit overall. Installation was straightforward but took longer than expected due to tight tolerances. Once on, performance is excellent—great for high-torque setups. Just wish instructions were a bit clearer.
Abag********otte
Solid upgrade! Took about 3 hours to install with basic tools. Runs quiet and handles torque like a boss. Only docked a star because the instructions could use more pics – I had to YouTube my way through one step.
Sha*******hold
Great kit, but the instructions could use more diagrams. Once I figured it out, performance was stellar. Runs smooth under heavy load. Solid 4 stars.
Grah********nger
Didn’t think much about axles until I tried this kit. Now I get it. The difference in torque and articulation is night and day. My TRX4M climbs like a mountain goat now. Clean fitment, clean look, no fuss.
