I would love to pickup that set with 4.56's but can't justify it after I stole a set of 4.10's with a Dana 60 front for $300 a couple months ago. I can easily justify it to myself but my accountant would be a little more skeptical.

You have to be much more careful with gear changes behind a diesel as they have a more narrow RPM range than the gassers. Those 4.56 gears would be too deep for a PSD with 35"s but maybe not deep enough for a gasser with the same 35"s if the gas rig was going to be towing heavy, then 4.88 or even 5.13 gears would help the gas hog more.

I have 4.10's w/ 35's and I run 2000 rpms at 65mph with the 7.3 to give you an idea.

Thanks for all those who search Craigslist for those of us who don't know all the tricks. Appreciate it. Now to start saving for tires...

Congratulations! That explains why he never contacted me back.

Didn't mean to grab them out from under you. I contacted him right after I saw the post by text and email. Pictures look ok, can't tell if they are just dirty around the centers or if there is pitting and oxidation. I will know more after seeing them in person. If they don't work out, I will let you know.
