Check out LMC trucks out of Kansas for the dually fender extensions and Arrowcraft for the wheels and spacer conversion. Google search srw to dually conversion kits.
Just wanted to say thanks to everyone.
I have a 2006 F350 4x4 dually.
Because of the MKW Model 26 rims, I have to rotate them
1 2
3456
Rotate
2 1
6543
in that order. The two MKW will not work on the front and the two inside are Ford stock rims.
I hope this helps.
