Rotor/Diff Swap

[quadhauler]

I like the late model wheels and I need a posi 3.40 in the rear of my 2WD '93 1500. Is it possible to swap the rotors and differential to late models on this truck? If so, is it a bolt in? Do the calipers and spindles have to be replaced too? Thanks!

3.40?

Cool ZR2: With all the stuff in your sig, you ought to know what that is.

ZR2... sorry for the smart comment last night, I was a little peeved (about something else) last night when I responded..... what I should have said was 3.40:1 gear ratio.... actually, the factory may be 3.42:1. Sorry.

If I had to swap rear end assemby I would scrap the 3.42's and find a 3.73 or 4.10 rear axle equipped the way you want and regear front axle. 3.42's are not a good choice for a heavy truck even with stock tires.
