I'm wondering if rear leaf springs (with overload) will interchange from a 2006 f-250 super duty (5.4 gas reg. cab) to a 1999 f-250 super duty diesel supercab? Also do you know if napa or oriellys stock the u-bolts? mine are really rusted. Thanks.

 

yep, they bolt right up

I did this with my Excursion about 1 yr ago. 2005-2007 trucks have different code rates from 99-04 trucks, but they're the same dimensionally

 

Yup, everything will be a direct fit. Basically take off your old and replace with the newer 06 springs.

I can supply you with U-bolts. We bend all our U-bolts in house. The ones you would be in need of are made of Grade 8 material with Grade 8 Washers & Nuts. Stay away from the lower grade U-bolts that some auto places sell, they are junk.
