I am running 35's on my d30 front. I built my rig to use and I am counting on finesse to keep from breaking it. Besides the worst that could happen is you would have to buy a D44 for the front, it's only $1500.

by the way, I did need new drive shafts with the 4" lift..on my 2 dr.

 

capt scotty- What type of drive shafts did you upgrade to?

 

I had a local shop make them. they use standard yokes and flanges that are easier to find than the custom adapters that come with most after market drop ins. They are 1310 U joints I paid $700. for both shafts installed.
