I have a 2010 Lariat supercab 4X2. I'm wanting to swap out my rear springs with the max towing springs or good aftermarket heavy towing/load springs. Any ideas where or what? I want to keep OEM as possible I'm not one for adding all the "sporty" stuff. A truck is a truck for me just call me old school.
You can have a spring shop add a couple of leafs to your existing rear springs cheaper than the max payload springs from Ford. I priced max payload springs and they were in excess of $170 each with my discount.
