i had a 1200 lb rock in the back for a week. I agree though i do need to wheel more!Super Doody said:My were like yours for two weeks. You just have wheel you truck more. Also putting 500 lbs of lugage in the back also helps. You just have to break them in. Put a couple hundreds pounds of cemment bags in the back of your truck for a wheel. They will soften up. Did you upgrade tires at the same time? That could also be a factor. I went from stock rugged trails to 10 ply MTRs. Offroad tires ride stiffer.
