I'm running ome lift stuts and coils up front I love them their the stiffer ones but I have a badlands offroad bumper and a winch so it evened it out. It rides great eats up potholes and washboards on dirt roads fine. There is however little to no flex in them, not that ifs has much but a lifted 86-95 ifs rig has more flex up front then I do. For the rear I'm running fj80s and its just a tad higher in the back then the front.
