If you're 4wd you will need to change the front ring and pinion gears to match also.TL: DR
Also, I started shopping for rebuild kits for the rear end since I have that leaking seal, might as well rebuild the whole thing and put an Auburn Select-a-loc diff in it. Anyone rebuild their rear end?
And now if I'm going to be in there doing all of that, maybe change to a 3.55 or maybe even 3.73(but that'll kill my mpg at 70+ crossing the country) I think I'd be pushing almost 2,000 RPM instead of 1700 like the 3.42's.
The only reason I even think about it is because the slightly larger tires and it's a dog off the line until about 4000 RPM...
All that being said, I'm sure I'm overthinking things especially given that once the blower goes on it'll be making a lot more torque and will make the converter seem like it has a higher stall which should alleviate any of that 0-30 sluggishness.
Ashamed these front diffs are glass. I would love to be able to plop a locker in that thing as well. Just like adding a winch down the line, the stuff I do I would likely never need it, but it would be really good to know that I have it if I did.
So I'll likely just wait on the gears as I'll probably be happy with them in the end.
Also starting to look into mounting the trans cooler sort of lower and behind the bumper with a fan on it especially once I have to put the after cooler in front of the condenser and radiator.
I have 4.10s in the 02 mustang and it runs around 2200-2300 rpm at 70 on the highway, but the 4.6 motor makes power higher in the rpms anyway.
