From what ive heard Ford racing makes a 4.30 ratio but only for 2wd trucks.
Haven't heard anything about 4wd?

I would be all over that with my 33's!
Don't eer plan on going to 35's so 4.56 would be to high for me and with 3.73's going to 4.10's would be much of a difference.
Now 4.30's, would fit the bill!

 

Nobody makes a reverse cut 4.30 for the front 8.8 axle. That's why the 4wd options are only 4.10 or 4.56

 

And that's the sucky part.... Even if it was a limited promotion i'd buy them in a heartbeat...

 

i have been throwing around the idea of regearing my truck from 3.73s to 4.10s also and I'm only running 33s but would it help with towing? and I'm running right at 2k going 75 on the interstate would my mpgs be really affected in town or highway because i wouldn't want to make it worse.

 

My opinion, 3.73's to 4.10 is not worth the cost as any butt dyno performance increase would be negligible. Put money aside and the answer is yes, there's a difference. But you'll have to make that choice. I wouldn't. Odds are, your mpg's would stay the same or only extremely slightly improve. Again, I'd you're using the mpg increase as a selling point, it's still a losing proposition.

 

Ya, it takes the pinion 4.10 turns to turn the ring gear once, or (it takes your driveshaft 4.10 turns to turn your tires around one complete turn). It all depends what your going to be doing and how hard it is on your motor to turn your tires. I know plenty of people that just run 4.10s and have 40s and they do just fine. I know someone that just put a 5 spd in his with stock gearing and runs 38.5 boggers and it still pulls good. He's going to bump up to 4.10s though. Its all about preference. I would think you'll be fine with 4.10s if your only runnin 35s.
