How Big Should I Go
 

ok the deal is a friend of mine has a 2005 2500 cummins he wants to put a lift on it he is lookin at either a 4 or a 6 inch lift he wants at least 35's would like 37's so my question is can he fit 35's with a 4 inch also if he did go with the 6 will 37's fit and are their any other mods he would have to do to his truck for it to work

Should fit with either of those lifts

To me the 6" on a Dodge with 37's is perfect.

35's fit with just a levelling kit, and for 37's you need a 4.5" or higher...

i have 35's with a leveling kit

My opinion
 

The 6"er and the 37"er's are a great combo, my friend has the 07 5.9 and it is sharp!! :dmi:

what would be needed to clear 40's? and where can i find a lift for that? as far as i see i can go with a 8" rize kit, and a 3" body lift. does anyone have any other better sugestions?

no body lift thats my suggestion.

then where can i find a 10"+ lift for a dodge? havent seen anything other than airbag lifts. and why do you not reccomend a body lift?

BL to me are cheap, there fine on an old gas truck

but on a diesel you have to mess with the intercooler piping, not worth the $100, plus the ugly gaps:booo:
