Just installed them in my trx4m bronco and absolutely love the look and performance

David R Alms

I'm really impressed with these axles! They were easy to install, but I did notice that the rear links required two screws instead of one. A major issue I encountered was that the screws need to be lock-tightened and screwed in tightly.

Greg Cogill

Well made, great addition to my TRX4M

These axles are amazing. The titanium color is show worthy. My go to are the portals but I decided to switch for a build and I'm glad I did.

Good axles

The axles are good, but mine didn't come with the brass tie rod end caps. I asked a question but still haven't received an answer. That's why I only got 4 stars.

Some of the best axles

Only thing I complain about these is there is no instructions to put together but they are pretty simple to put together but these axles are so good with the really good turning angel and the width is perfect overall really good
