I have fleece lines in two trucks for over a year In one and bout 6 months in the other.01 and 07.5 they are both doing great with them no leaks easy install would totally get another set.
Not even 10k miles and my fleece lines are leaking already, 300 bux down the drain.
The thing about the drp lines is it's literally just parker high pressure hydraulic hose and fittings made into a kit. If you ever were to have a problem you could have a line made pretty cheap or if you can get a deal through parker you could make your own lines.
i just dont like how big and cumbersome they are. they dont fit in there nicely like stock ones do. you really gotta put some time into getting them in there, keeping them off rub points, and cinching them down.
