i lowered my truck 4/6 inches which meant i had to go from 27 inch diameter tires to 25 inch diameter(rim & tire) to keep the tires from rubbing the inside of the wheel well. what sucks is that i have 3.42 gears and couple that with the smaller tires which equals slow as $hit acceleration. what gears should i go with now?? or should i try to fit bigger tires? how much are gears nowadays? what kind? how much on install? thanks!!!
