got mine done locally for $1000 installed for gears/locker. you might be able to find it a little cheaper.

 

I got mine parts and labor for $800. Tomsdifferentials.com seems to be the most reliable store and has great service as well. Just make sure you get the right carrier bearings before you pull everything out <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" /> Also it did not hurt my gas mileage enough for me to notice at all. I would go with 4.10 over 3.73 any day. And yes traction sux even with 25 psi but I might try some Autozone traction bars and new tires.

 

Has anyone changed gears from 3.73 to 4.10? I have 3.73 and I have been happy with them but if changing to 4.10's would help alot I would consider it. How may rpm difference would I have at 70mph?

Rpm's at 70 in my truck are just at 2300,that's with a 29.4 inch tire.

 

that would be considering you had the same motor and shift points in your truck as he does.

Those won't make any difference at all. You could have a 4 cyl honda shifting at 7500 rpms but as long as it had 4.10 gears, 29.4" tires and a .70:1 overdrive, it would be seeing 70 mph @ about 2300 rpms, just like ranwalk.

you cant possibly think that if this guy is spinning 3800 rpm in a 4.8 vs a 6.0 that this isn't going to factor in expecialy to his gas mileage <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

Did I miss something? Where did 3800rpm come from? What are you talking about?

I'm not trying to flame here dude, but you might want to let people who have done the swap or is knowledgeable about the swap give the advice. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

 

Duh! You think? <img border="0" alt="[jester]" title="" src="graemlins/gr_jest.gif" />
