dvldog458, first off nice truck. But there is a significant difference between Whiplash's truck and yours. Yours has a dana 50 ttb front axle which is stronger than 97 and newer 1/2 ton CVs. You can run alot larger tire on a dana 50 ttb as compared to a IFS CV.

 

My mistake,i was thinking of old school F-150's.I didn't realize they changed so much.
