Dually lift
 

Hey

So I am sure this has been asked before but I could not find a good answer too it.

I have a 2001 F350 extra cab 6.8L V10. I am interested in installing a 3.5-4 inch lift. Every lift I look at says its not for "dually".

Far as I know there may or may not be a difference in rear spring width?? Also i think the rear axle tube width may be different. Does anyone know of a company that offers a lift for a Dually?

I would like a lift that will give me years of trouble free use and WITHOUT blocks! I will still be using my truck to tow heavy loads so must retain weight carrying capacity as well

Thanks for your help

Nobody knows anything about lifting a dually???
