I had my 4.10's, TT and Mag-Hytec diff. cover installed by AZ Differential in Phoenix. I dropped my Titan off yesterday and had it back within 7 hours, for only $1,100 installed.

Awesome customer service! If you need any differential work, tranny work etc. Give them a call and ask for Nate. Amazing guy who knows his stuff!

I would never go anywhere else. Top quality in everything they do.

I had to write them a little review on here because I'm blown away. It's rare to find places like this anymore. Very happy! :D

World of difference! I had contemplated a Dana 60, but realized I just didn't need it with only 35's. Happy I didn't go with it and saved that money.

TT - I haven't been able to really test it out yet except on the wet pavement this weekend. I must say, hella fun! Can't wait to hit dirt. I could feel the constant power coming from both tires. I would always get the slip light on wet roads. Not anymore.

Gears - I'm still in the break in period. The first 500-1,000 miles, no towing, no heavy acceleration, no long trips etc. I'm at 150 miles in 2 days. I'm probably a little more cautious than I need to be. Don't want to void the warranty during break in. One expensive mistake. I also have to change the tranny oil around 750 miles. After I see there's no shavings and everything looks good, I'll start accelerating "heavy". That word is a little subjective though.

It feels like a whole new rear end. Much more "beefy/meaty". I can feel it pull extremely hard.

I have accelerated it semi-heavy. Absolute sex.. :D

I've got 35x12.5/20 Trail Grapplers. The speedometer seems to be close to accurate now, +/- 1mph... Based off the electronic "your speed" signs.

I took down some numbers...

MPH - RPM

50 - 1,800
60 - 2,200
70 - 2,500
80 - 3,000

And yes, 44HD.

Forgot to mention with the new diff. cover, it runs about 20-30* cooler than what is used to.

Nice to see another arizona diff Titan. Love that place. I've been contemplating going up there in a few weeks for the mag diff cover.

We're talking parts and labor here, right? If that's the case, I'll seriously consider it myself. Otherwise $1.1k is a lot of money for an hour or so of labor.

Ouch 2500 rpms at 70... How's that affected your mileage?

The exact price was $1,095, that's with a 10% discount. (If you mention TitanTalk.com, they will give you 10% off.) That included, TT, gears, labor and taxes.

I had a Mag Hytec diff cover, I bought that straight from Mag Hytec. That was $240. Once they were finished up they threw it on. You can also buy the diff cover from AZ diff., but I already had mine sitting in the garage prior to going to AZ Diff.

Not bad at all. Well, I don't drive on the highway that much. I live in the heart of everything. So I can't really speak on that subject to much. As of right now (only at 400 miles) I don't notice any difference in mpg.

My idling RPM's are 1,000 - 1,200 depending on the temperature. So for me 2,500 doesn't seem that bad.

Was the cruise control maintained with this conversion?

Nope it was not, which isn't a problem for me at all. I've used it once in the last year. I live in the city though.

The highest you can go and still have cruise control is 3.73.

Just wanted to say... after almost 1,000 miles of driving with the new gears, my MPG went up 1 lol.

I can get about 25 more miles on a tank if that counts for anything.

Is that highway driving or just around town? I figured it would improve around town a little.

I'd be willing to do this - if I could also get 4.10s for the M205 front diff...
