Here's what I'm thinking for the rear suspension. A double triangulated 4 link with skyjacker nitro shocks and 5.5" lift jeep zj springs. The springs have an 18" unloaded height and 180lb spring rate. If anyone has any ideas or other info it would be greatly appreciated. I am going to keep the wheel base the same and the weight in the back will be both propane tanks, a cooler and a spare tire. I'm going to be purchasing the parts within the next month so I need to pull the trigger on my suspension choice. My other option is to go with 16" 2.0 air shocks.
