Thank you for your question. Depending on the truck you have I would recommend the pro comp MX6 adjustable found here http://jo.my/o1jyz8 . This will allow you to adjust for the extra weight. A coil or strut spacer would help to preload the suspension to regain the ride height. The Bilstein 5100 ride height adjustable would be a good choice for an IFS application. After installing the bumper you should allow a few weeks to see how the springs settle with the extra weight before deciding on the adjustment you need to make. Remember a winch addition will add weight as well.
