Maybe I'm in the right place now. I want to fit a 18 inch tire under my d150. To do this move springs inside frame ? Under frame ? Or ladder bar set up what would be best ? And as far as axles go to go along with this way is best I have heard an 8 3/4 A bodybaxle good, bad, suggestions ? Thanks guys I can't find info anywhere.

 

What vehicle are you referring to? Please add your vehicle info (year, model, engine size, transmission, 2 or 4 wd, etc) to your signature so we don't have to guess.

 

Sorry new to this 1990 d150 318 trans?

 

Awesome. Thank you. The more details you can add always makes it easier for someone to offer assistance.

 

I don't think you have the much room between the frame rail, and the outer fender. Could flare the fenders?
