This was done successfully if you search for " SAS". He had to use a GM front axle though because if you're going to convert your truck you might as well go SFA and not IFS since it's less complicated and you can't use a dodge front axle because the Dana 44s are too weak for the 3rd gen and I don't think a 2500/3500 one is compatible

 

4.7 will bolt to same tranny? And does the suspension and everything bolt right up?

 

No, the suspension does not bolt right up. Cutting and welding will be required. Cheaper/easier to just buy a 4x4 truck, and sell your 2wd.

 

02-05 2wd uses front coil springs with shocks, the 02-05 4wd uses torsion bars and shocks. Good luck with that lol.
