received my trex no-cut frame sliders today and installed them tonight, along with changing the oil. Install was pretty simple, removing plastics was the hardest part. I know a lot of people say cut sliders are much better, but these things are pretty sturdy, couldn't believe how much the box weighed when i grabbed it off the front door. The brackets that bolt to the frame are very thick/sturdy. To be honest, i don't know how these could be much weaker than regular sliders, the brackets bolt to the exact same spot in the motor mount that cut sliders do, and they seem very well built. Anyway, here are the pics after install
