Here is our 05+ super duty axle swap kit that includes a universal 4 link as well if you don’t want to do the radius arms and want more adjustability here you go! Everything is cut from 1/4” steel mig welded for great durability and longevity! This kit with the 4 link can accommodate up to 8” of lift after that it would need to have the long arms instead. Heims are 1.25” for the 4 link arms and the trac bar uses 7/8 heims, Any questions feel free to ask!
