Want to make my truck a Dually

I have a 1999 F250 2wd supercab short bed truck. What I want to do is put a Dual wheel rearend under it to tow my 5th wheel camper. I have to chance to buy a 1999 F350 with the dually rearend it is a 4wd truck. My question is will this be a direct bolt in to my truck. Both trucks are 7.3. I will also be doing a 3"front lower and a 5" rear lower at the same time. any help with this would be great thanks

Well, the nice thing is that the gearing is probably different than what you have, but you have a two wheel drive truck so who cares. Check the ratio though, that dually may be a 4.11:1 and you definitely don't. Other things to check, spring pack width, driveshaft connection to rearend, it shouldn't be different, but check the distance between spring packs. What are you going to do with the front of your truck? If I remember correctly, the fronts only use a bolt on spacer to move the wheel mounting surface out to match that of the dually rear. That may just bolt right onto the front of your truck as it is. This is just by thoughts... I'm sure there are those more educated than I that will hopefully chime in. Good luck.

Be careful that you don't make your truck a criminal in your own neighborhood. It may not be enforced, at least consistantly, but many communities including mine have ordinances forbidding dual wheeled vehicles to be parked in a residential area. My neighbor's friend was displaced from his house due to the town adding lanes to the local parking lot (I-465), when he moved into the new home that he purchased a busy-body neighbor complained about his truck and trailer with backhoe being parked in his driveway. After it was all over he had to find another place to park the entire rig. Even the truck (dual wheeled pickup truck) was ruled commercial due to the dual wheels and restricted from being parked over night on the property.
