Yes there are kits out there. My question is why? I too like the way a 4wd looks, but you would be ruining a good vehicle. The benefits of a 2wd are better fuel mileage and better towing stability. Of course weight plays into it, but it is mostly due to less air drag (lower). Larger heavier tires will also hurt fuel mileage. Towing will suffer with a less stable ride. You will have all the negatives of a 4wd with none of the benefits. If you want to do it because you just want to, then go for it. My .02.
