Gears got stripped after one use. Had to buy another set
They have been strong and haven't failed. One set was noticeably notchy-er than the other when freshly assembled, which calls into question the machining tolerances. That has seemed to calm down after a bit of use though. I installed them in the front axle only of my TRX4M. That has helped with turning tight corners and getting up and over abrupt obstacles. It has hurt overall traction climbing smoother, steep slopes though. Not sure I would buy again but that may be more of a preference thing with my particular use case for my vehicle versus how other people plan to use theirs.
