Pretty easy, get the front gear set from the Power Wagon and a rear gear set from Precision Gear. I think the p/n for the front is 517528AA.
 
Randy's ring & pinion is where i got mine. why do you want to go with 4. 56??? if i did it again i'd go with 4. 10's with the 37's. race wise it's great but everyday driving i think theyre a little low.

I have the 4. 10's as a factory option with the Toyo 35's. Great for daily driving but as far as towing goes I think I need a little more.



Have you had your computer and or speedo calibrated with the gear change and tires? Is there a setting in the computer for gear ratio like the revs per mile? If not how did (can) you get your speedo right?



What are your rpm's at like 55-65ish? This is where I usually tow and I think that since we use are truck as a tow vehicle only type truck that 4. 56's would be perfect for this reason. Basically no 75-80 mph trips, we have to cars for that. thanks...

You hit it right on the nose, The same hill i got pulled over doing 80mph towing my 5er slowed me down to 48mph with my new 22. 5" Alcoas in which the tires are about 36. 5" tall plus I only have 3. 73 gears. I did find 4. 63 gears for a G. M. but I cant convince myself to do that or sell my 22. 5" Alcoas

55-65ish is below 2k in od, guess i didnt think about where your at, i just went sask. canada last week and the gears aren't good for 85-95 mph. still got between 14. 4 and 14. 8 mpg though.



i didnt reset anything on the computer, just put in the gears an drove it. i have my correct speed on my outlook monitor.
