I have a 2006 extended cab and my truck rides horribly. I love the way it looks, I love the interior, I love everything about my truck except the bouncy ride. I've considered going with the Sulastic Hangers to help this, but I don't know if they work, plus they are $400. I was told by Belltech that their "Street Perfomance" line of shocks smooths this problem out. Does anyone know anything about this? Or is there any other shocks that may help? I've tried putting the weight in the bed and it is only minimal help, plus it hurts my gas mileage... and I'm tired of people asking why I have bags of sand in my bed.
