Just finished installed my T-Rex frame sliders. Install could not have been easier. Added blue thread lock on all the bolts too. Also added washers inside the pass side slider to keep the end of the bolt away from the oil cap as was suggested.

Pics are here. Hope this helps someone else out

I have been looking for some kind of frame slider also.

Does it seem to be sturdy enough for a good spill?

The plates and sliders are very well made and heavy. Install was super easy and with everything bolted down, they seem really solid. I havent ridden with them yet though. Im waiting on other parts to come in and Im ordering new riding jeans here in the next day or so. But overall, Im happy with them
