Default rear axle/gearing question

so there is a guy here in town selling a dana 60 with posi. question i have is its got 4.11 gears. would that be too much gearing? ive seen some guys post they have 3.92 gearing, he's wanting $200. im thinking about getting it tomorrow, what do you guys think, would that be good gearing for a 4*4?

Go for it. If it's a 1500 and you have a 2wd truck you'll love them.

4.10 is perfect gearing but be aware its not a direct bolt in replacement on a 1500. you'll have to figure out springs, shackles, perches, and maybe drive shaft. if you can do this then $200 is a great price, they can go for $500-1000.

also if you have a 4wd, you MUST change the gearing in the front to match or else do not not not use 4wd.

also someone said my 46re sucks, and doing some searching on here you guys suggested either viper trannys or dr evils trannys. my question is what is a better stock replacment tranny that is still auto? like could i find a 2500 with the same engine ? or would it have the same tranny?

Parts will start to break quick with miss matched gear ratio's if you put it in 4wd

Nothing just re-read the above threads for all the needed mods to install a Dana 60 in a 1500

if you don't change the gearing in the front, and try to use 4wd, the truck will jump up and down all over the road and will be undriveable.

nothing wrong with a dana 60. zman is kicking himself in the *** with his one good leg because he missed your post that it was a d60 and he neglected to caution you that its not a direct fit swap with a 9.25

The viper and dr evil trans are auto's. The 2500's still use the same trans if they were a v8.

ok so what is a posi gear ratio that would work without having to screw with the front axle? I dont mind having to relocate things on a axle. did it in my 77 chevy when i put a posi rear from a 95 chevy. nothing new to me there.. also.. i have been thinking of forced induction. does anyone know the compression ration of the 5.9? I figured i could use the stock turbo off of the cummins if i couldnt find a decent aftermarket turbo.

I know what your gonna say.. trying to haul *** in his truck.. i just like turboing things.. like i said i did it to my R1 just because i could. anyway. if anyone knows those numbers that would be rad.
