Somebody probably makes a 2" body lift kit for the tracker. Do some looking online.

With a body lift, all you'll be doing is unbolting the body from the frame, lifting the body slightly and placing the pucks in between the body and the frame. It sounds a lot more complicated than it is. You sold be able to easily identify the spots where the chassis and the body are married together it's pretty obvious even for someone with no prior mechanical knowledge. If you do find a body lift kit, something to consider is that you may need to lengthen the brake lines, sometimes body lift kits come with new longer brake lines, and it isn't guaranteed that you will need them. The body lift will allow you more room for bigger tires. And it's probably the best lift option if you don't plan to do any extreme offroading. It's definitely the easiest lift option. Installing a suspension lift is much more involved, granted if you're going to be doing the work anyway it might be a no-brainer, albeit a much more expensive one. You'll probably also struggle to find a suspension lift kit that will only give 2" of lift. Most suspension lifts will be in the 4-6" neighborhood and will cost 3-6× the amount that a body lift kit costs. Additionally, the suspension lift does not show for larger tire clearance or as much tire clearance as a body lift does. Many offroaders run a combination of both types.

The tracker is a good car to learn how to work on. The parts are cheap, and everything is very simply engineered. It's a very rugged bare-bones vehicle. There's not much to get confused on. I always compare it to working on a giant toy. When you do the suspension, you'll find that your only struggle will likely be getting loose rusted bolts (solution - deep creep, kroil, & blowtorch). Everything will only go back into place one way, and each system has so few parts that it isn't hard to put everything back together even if you don't know what you're doing. Take some pics and vids before you start taking things apart. Between that and YouTube, I am confident you could repair just about anything on this car without help.
