“Installed in my 2006 Sierra 4x4, standard cab, short bed. It fit great without much additional bending. Routing brake lines on this truck is very tricky and takes some trial and error. The ABS pump on the frame rail has no space for all the lines and did take some slight hand bending to get all the fittings screwed in. I wish I had taken more pictures of routing before I started. The passenger side line seemed impossible to route at first and took me several tries. Unlike the factory line, this kit split it in two pieces which helped -I think I went in though the driver side wheel well first with the long section. The line to the rear also had a coupler in the middle -for the long bed you install a small extension piece. I did remove most the bed bolts and lifted the driver side of the bed up about 6in on wood blocks to make room for the rear line install. It took me a whole day just to install all the lines but I did it solo on jackstands with the front wheels off.”
