I had one in my DD trail rig, I highly recommend them! no scratches, I ran through trees, bush, and had tons of rocks hit it, I work n the oil field on a drilling rig, and there are always semis throwing rocks and gravel, well.... no chips, scratches, nothin!! it was easy to install, use a small rope, or twine, oil the new seal, and pull it into place! just like a back window of an old toyota or pick up truck. I rate it at a 9 on upgrades - 1 being lowest and 10 highest.
