I got one side of the undercarriage done today on the mt85. So far everything looks like good quality and is a tight fit. I have 500 hrs on it and a few of the pins needed to be replaced and the good pins I'm just changing the seals and adding more shims to decrease side to side movement. I would recommend this. Lowest price I found.
