So...I dont know jack about suspension. The suspention on my 83 k10 suburban is INCREDIBLY stiff and the truck rides incredibly rough. I know these aren't Cadillacs but something must be wrong. Buddies bone stock 84 C20 rides like a dream in comparison. In mine, you feel EVERY bump and up between 60-70mph it vibrates pretty good but not like, death wabble. It does not feel like a wheel / tire issue. The tires appear to be wearing evenly and have no cupping or knots. I don't think it's been lifted. But, the front of my truck currently sits a bit higher than the rear. Would it need to have been lifted to keep 32s from rubbing? Did the 6.2 trucks have stiffer suspension? Where should I look first?
