I have a 2019 Ram 1500 4x4 Quad Cab with a 6/4 bed.I have learned the hard way there is a difference.I first installed a Wulf 3 inch front spacer and a 2 inch rear spacer without new UCA that was a problem and the ride was not that good.Then Mopar came out with there kit .I had my dealer remove old and install there kit.I really loved how it looked and road except on curvy roads the ESC traction control engages and brakes.The dealer replaced speed sensors,steering angle sensor yaw sensor.Even escalated to a Star FCA case.Months later they have determined they kit is not compatible with my truck and are going to remove it and return my truck to stock.Any body with a Quad Cab have any input on options.I am fried dealing with this .Thanks
