I already have a one ton 3500 and the long bed.
I just want the capacity for the rear tires, I'm not worried about changing the registered weight or GVWR on the sticker or any of that, just the capacity since my 5th wheel trailer really pushes my rear tires near the limit with all the stuff I carry in the bed and my tool box.
Rear spacers
Fenders
Front spacers
Is that it?
i run billet steel spacers and sled pull my truck all the time with no problems. the aluminum ones are about 120 the billet steel are 350-500 depending on thickness
