I have a 91 3.0/5 speed extended cab pickup. I love it to death its an animal in the hills and aside from add a leafs in the rear its bone stock. overall I really have no complaints at all but sometimes when I am out hunting or something I come across a hill thats just too steep. or just a little too much snow. I can always put it in low range and be fine but I was wondering if there are any moderate bolt on mods that are worth it with these trucks to give me a little more umph. i run 31x 10.5's btw
