Well, the lines are nice and appear to be of high quality, but this is far from a full set replacing all of the Grand Cherokee's lines. I knew the 4 short rubber lines to the calipers are not part of this kit but there are 2 pull back lines for the front corners and then the rear center line which are also not included in this kit. So if you know what's ahead, you're good. Remember. Also, for some reason the delivery was delayed and a few days late (this was an issue with Revain delivery, not Dorman). I ended up returning this kit as it didn't have everything I needed and I was able to spend less and just pick up the parts I needed elsewhere.
