I had mine done here in Texas at KS Conversions. I love it and no regets at all. I don't know how much it changed the turning raduis because I drove it from the dealer to Kadale but it changed the wheel base from 160" to 180" and my 99 f350 4x4 was 172" wheel base. The extra 20 inches also makes the truck ride better. The dodge can still out turn the ford. The longbed makes the truck look more balanced and alot better looking IMO
