I have a Ride Control kit part number 59542 (a new set can be seen at this web page http://www.airliftcompany.com/new-index/Frameset.htm )
I also have the Load controller II with the sigle gauge and compressor, lines and all fittings. This was on my truck for mayby 2 months befor I bought a larger truck and had no need for them anymore. I had this on a 2002 4X4 F-150 with a fifth wheel hitch and it worked great leveling the truck to the trailer.
new price is about $395.00 Im asking $200.00 plus shipping.

email me if interested
