I just got an '18 King Ranch. I put a Fox Adjustable leveling kit with Bilstein 5100's all around. It definitely gave it better road manners and tightened up the ride. Loving the quiet of a truck on road tires. My '14 Lariat has a 6" BDS Lift, Fox coilovers, 4.10 gears and
Toyo 35" R/T's. Just a shout out on those tires. I just put on the third pair ( 130k miles) Both sets lasted 65k, and had > 20k left on them. They just get a little loud at that point. Stuck with that '14, cause it's worth way more to me than book. Drove all the $$ value out of that.
