I see. Well now you guys need to help find me a 3.55 rear from 1990s model dually someone who wants to trade and I go ahead with that site donation. You guys have been very helpful. Last question has any of you had experience with both? What differences did you see?

I'm just wandering if anyone has dealt with this and seen significant change in full mileage the rpm is obvious. It should make turbo respond better or different.

I just replaced my 4.10 for a 3.55 and i wouldnt say it was a huge difference. With 285 tires i can run 65 at about 2000 rpm, with the 4.10 i think it was 60 at 2000. I didnt notice any difference with turbo spool, I wouldnt think it would matter except in first gear towing a heavy load. I have towed my trailer since the change with no problems. My trailer isnt real heavy. I havent calculated milege yet. Overall i like the change, better freeway speeds and a little more speed out of first gear.

What
you mean?? Do you know of aftermarket gear co, that makes them? I install gears on my drag car and the setup has to be similar to that? I would think I should be able to just find someone who's willing to swap rear ends or junk yard item? I need more Mpg's out of the truck plus easier towing, I believe the 3.55's will help a little for both. In the future I'm going to do a lot to the truck, I have good tires on it that's why bigger tires are not an option right now. 235 85's!!
