I haven't lowered mine yet just because I haven't decided the best way. I only want to go 4 inches in the back but I also use my truck for hauling loads and want to put helper bags on it. My plans are to install a Pierce dump cylinder kit so I can haul gravel also.I have only found the Tin Works...
Bought the truck last fall and it has been so useful around the property for projects with the 8 foot bed. Love riding the dogs in it too. I want to lower it some, fix everything that doesn't work, and put some cam in it with loud exhaust so it sounds cool.
