I see that it will now allow you to build a 3500 SRW with 4.10 gears on the Build Tool. Has anyone actually been able to order or purchase one like that? That would be really nice for those of us that want to run 37s.

We did, on a gasser. But if it's on the Build and Price for a diesel, they should be available.
And nice for towing, with stock size tires.

Then I'd do the Build and Price thing, write down the options, prices and some notes, then get the real option list from your dealer and go over it.
Yes, it can be a bit time consuming, but that way you'll get exactly what you want, or at least as close to it as conflicting options allow.

So, they built my order yesterday and the 4.10s were a no go with an SRW diesel.

Going o place my order this morning for a Longhorn Megacab with (unfortunately) 3.73 gears.

Related note: I finally got to crawl around and drive a new truck. It was a 3500 SRW 4wd Laramie with the 12" screen. Amazing how tight the truck was and how good the front end rode for stock. Adding Thuren coils, Kings, and larger tires so I can run them at 50psi front and 40psi rear is going to make for a crazy comfortable truck.

I ordered them on my build and price for my 19 and was told at the last minute from my dealer no go. Only 3.73’s are available on a SRW at this time period. I’m running 35’s and the torque is so impressive I’m glad I wasn’t able to get 4:10’s. If your getting 37’s and towing extremely heavy you just might want to do an aftermarket re gear but even then with all the torque the 3:73 should work well.

Thanks for the feedback.

I have not searched extensively yet, but I'm finding nothing in the way of aftermarket gears or lockers for our 12" rear end. Certainly that will change soon but for right now, us SRW guys seem "stuck" with 3.73 clutch type LSD. I can say that I've put mine through the paces towing off road and the rear end does hook up both tires in the slop. Almost as well as my old 11.5 AAM G80 auto mechanical lockers on my old duramaxes. Also, I agree that with this much torque, 3.73 are more than adequate for running 35's heavy.

You can get 4:10 gears with a Tradesmen 6.7/Aisin combo with DRW. I just got one is why I know.

Arent 4.10's common on duallies with the HO 6.7/AISIN

No, because there were others on the lot with 3:42, 3:73, if I remember correctly on the ratio. They were trying to sell me one with out the 4:10’s and I wanted them due to the fact I just haul all the time.

They are as common as whoever orders the vehicle(s) want them to be.

As pointed out above, they can be had with any of the three ratios, but I would guess that only a dealer would order 3.42s on purpose.

But what’s most common? I think all ‘19 SRW with the HO/AISIN have 3.73. I could be wrong.

If I had to guess, I'd say that 3.73s are the most common. Mainly because that would be one less option a dealer would have to think about picking.

And, yes, with SRWs 3.73s are it. No choice there.

I feel like we are being disingenuous when we have serious conversations.

Right you are.
Long live 3.42s and tall tires for towing heavy!

Better?

I honestly couldn’t imagine pulling any heavy loads with the 3:42 or per say the old 3:54 axle gears, even with the Aisin. This is just my opinion and experience.

Didn’t they get rid of 3.42s all together for 19? I thought it was 3.73 only for SRW and 3.73 or 4.10 for duallies?
