      Replacing a line was bad

      Good product have been using your line set since replacing factory lines , only reason for replacing was knee had dropped down a little over time and the steering damper stud was rubbing the line which was the one that went to the bottom of radiator

      Trans issues after line swap.

      I replaced my leaking stock lines on my lbz with these. Replaced fluid and filters at the same time. Now my trans is slipping and temps are extremely higher than before. I was told by a reputable trans shop that the 90* fittings could be an issue. Can someone email me the size of the fittings so i can replace them all with 45* or sweeping 90s? I can update my review after that to advise if this is my actual issue.

      Harder than expected

      It took much longer than expected. Change instructions to 4-6 hours. Cutting existing lines and removal was harder than expected. Instructions should also say to remove right fender well along with front skid plate for better access to fittings. Be careful when putting fittings into radiator, if you install 1 at a time and tighten then antifreeze will go everywhere if internal lines is dislodged.

      Heavy Duty

      Just installed the 1/2 inch lines. Great instructions and pretty straightforward install. I haven’t done much work on my truck but it’s pretty much new plumbing so I felt comfortable tackling it!
