None of the aftermarkets we installed in 1500s or Dakotas made any more or less noise then ones over the parts counter at the dealer .Wouldn't be surprised if they came from the same vendor.Did siome Danas in diesels from 3.55 to 4.10 with aftermarket including my own W250 with no issues using master overhaul kits.

No such thing as optimising for 4.10... the car still needs to shift at the same rpm... the ONLY thing that may need work is if you are flaring over max RPM.
No need to reprogram for gears... didn't need it on the previous gen either...
Given that most cars have gps there should be a way to set your cruise on a flat road and get the car to recalibrate based on the speed indicated by the satellites (for tire changess that is).

You may wish to inform the techs at Superchips of this, as I'm simply restating what the owner's manual says.

I installed AAM 4.10's in my 2010 2500 to replace 3.73's.
Lost a solid 1-2 MPG overall (mostly city driving).
Gained a lot of get up and go, made towing a bit better.
They were the noisiest damn things Ive ever heard. From 50 to 75 MPH they whined like crazy.
I just removed them and went back to the factory 3.73's. I'm so happy to have my nice quiet truck back.

Well... if you are the sort of person who would buy a superchips product, you are the sort of person who belives their documentation, even if it is blatently wrong... the only reason to ever change programming for gearing is for speedo, which is NA in this case or if your vehicle is accelerating so hard that it will over rev into the rev limiter if you do not lower shift points, which is sure as hell not happening in a truck stock enough for a superchips to work on.

I had a tour of the GM axle plant in St Catherines years ago. The guy assembling rear end gearsets could put them together in less than a minute. That's all he would do for the entire shift. Someone changing gears on an occasional basis will have a lot harder time getting them "right".

Are the Mopar ones really any different than AAM gears? It is an AAM axle I believe. Shouldnt those be the ones to get?
Oh, my speedo was dead on with both sets of gears. I didnt have to change anything.
