Another jumping to the 4th Gen

New 11.5 inch Rear Axle

The stress is only where the pinion and ring gear meet. The trans will save itself but the rear end only transmits the RPM to the axle.
 
I think we are all over-thinking this issue. My truck pulls my heavy RV extremely well despite having 3. 42's and in my case, is only one weekend a month. My 12' enclosed trailer is my primary purpose for the new truck and it doesn't even know it is hooked up..... even at 5k lbs. Heck, I'm more concerned with the POS factory Firestone's than anything else. The ring gear is 11. 5" in diameter guys..... why are we really concerned about the rear end at all!! I'm not! It's an entire 1" larger than my previous 2nd Gen. Dana 70 w/3. 55's and 33s... . which is probably real close to the actual final drive ratio of my new truck with the smallish factory tires.

Instead of finding fault with the 3. 42's ... . instead, let's take a look at the obvious advantages. How often do MOST people tow to maximum GCWR? My guess is not many. For those that do, by all means, get the 4. 10 geared 3500 dually and be happy. For me and many others, I feel like I made a wise business decision by choosing a 2500 w/3. 42's. Unloaded mileage seems to be very close to my modded 2nd Gen... . loaded mileage is exactly the same. That is taking into consideration that the Cummins is nowhere near broke in. If I have to take off a little slower about once a month while hooked to my RV, it seems like a worthwhile alternative to buzzing my new 6. 7 to over 2k rpm while cruising down the highway.

Harvey... ... the 2013 is really a well built and well designed rig with plenty of power and torque. I test drove one and had to have it! Go drive one..... I can almost guarantee you will be satisfied.
 
I thought I was gambling with the 3:73, but with the three different ratios available, with the 3:73 middle of the road, I guess I'm safe. :)

X2... I tow heavy in the city, 30K+ and Yes HB its legal, But this winter went I hit the Rockies May tell another factor,,, But For NOW My 13s have preformed well. Hopefully they stay that way.
 
Then your hauling a camper, with 3:42 you will wear the pinion/ring, just not as fast. Remember this thread in five years, when the diffs start to fail equipped with 3:42 gears. AAM can't change the physics in turning a gear any differently than in 07, but they can add a cover that helps dissipate the heat better to rid the diff of the extra heat generated.
 
The Powertrain Integration Manager, Jamie Standring, told me that pulling a trailer he would go into tow/haul mode, but might not bother if the truck was solo and loaded to GVWR.



Ram adds the cover with Max Tow meaning the dually with 4. 10. I'll take that bet--I don't think the diffs will fail; just use good lube. If Jamie isn't worried about trans fluid heat from the torque converter helping the load get moving, I expect he has done enough testing to back up his position. Again, I think most buyers of the 3500 SRW won't be at the GCWR most of the time. If you want to be safe, pay the extra and get the Aisin. Then you have "too good" a trans to go with the "too good for a pickup" Cummins. As I looked at USA-wide inventory of SRW 3500s, and even at dually Rams, I was amazed at how many were ordered with expensive gingerbread but not with the Aisin. I have never been disappointed by something that was "too strong" or "too durable" but I have seen problems from getting components that were "improved" and "adequate. "

If you like everything else about the truck and the 3. 42's are holding you back then buy a DRW or do a gear swap... maybe you say that Ram should just provide the options and to a point I can agree but it is what it is and they didn't change it for the 2014MY...



What if you don't tow, but haul with a 3500 DRW at close to the maximum GVWR?



Bill



you can still order 3. 73's and 4. 10's in DRW applications regardless of transmission.

My sons new 13 mega DRW with Aisin and 3. 73 came with the finned aluminum rear cover. It has 1200 miles on it in just over a week. Pulled a 07 Ram 3500 on a flat deck approx 300 miles. truck/float approx 10500-11000lbs. He said you could not tell it was behind unless you looked in the mirror:D. Haven't heard his mileage yet.

Yep, I noticed the same thing with 3500 dually trucks in my area... many with fancy gadgets in the cab, but no Aisin transmissions. If I traded, it would be an ordered truck with an Aisin and all the engine power I could get. There are two things that one cannot get enough of in a pickup, (1) engine power and (2) a bullet proof transmission to handle the power. Of all the diesel powered pickups I've owned, both Ford and Dodge, only one didn't have a 4. 10 ratio, and I swore after owning that one, never again anything but a 4. 10.

As posted earlier, I was worried about my choice of the 3:73, because I had planned to tow heavy, in fact I had registered it for 26K. The plan was for the truck to be set up as a service truck, to drive in city traffic 50% of the time and RV hauling during the winter 50% of the time. So it made since to order it with the 3:73, I was happy with my 04. 5 with a 3:73 but never towed at max GCVWR. I believe Dodge is just trying to increase the COLA ratings and are gambling they make it thru the warranty. A good example of how manufactures get around regulations, have you ever wondered why there is a switch inside your refrigerator and asks you to turn it on under certain conditions? That switch turns on door heaters to prevent sweating when high humidity is present and the reason they ask you to turn it on and off manually, is the energy it uses won't count in the energy efficiency calculation because its manually operated, helping to meet the regulations.

I wish you guys the best of luck with the 3:42, after paying 50K+ :eek:, hell it should crap gold for that amount.
 
I too wanted to order a SRW 3500 with 4. 10 but Jamie's discussion was helpful. My usage doesn't include very heavy towing, or towing all the time, so 3. 42 should work fine, and test out that 100K powertrain warranty (not that I really have any doubt that the Aisin etc. will hold up). Sure, 50K is a lot of money even with the inflation that our gov't tells us isn't happening. However, a lot of us ended up with that much or more in our older trucks by the time we modified them to suit us. Today's Rams hopefully will need a lot less owner-added stuff and have the added benefit of some beef that we couldn't get in the old days--stronger frame, big brakes, Aisin trans, 385 HP with a warranty, heavier axles, etc.
 
I will give Ram credit for one thing - they are pushing those informed individuals who are buying the truck to tow heavy 5th wheels or goosenecks away from the 2500 and 3500 SRW trucks that generally don't have the GVWR for the job. Unfortunately, all too many buyers still aren't informed and are going to be buying 3. 42-equipped 2500s to tow 18,000 lb. GVWR 5th wheels because that's the truck sitting on the lot and it comes with the dealer salesman's blessing that the "mighty Cummins" can tow anything.

USA powertrain warranty is 5 years, 100,000 miles and does not specify which transmission. Manual clutch components are 12 months/12000 miles.
 
( 2013 DRW Mega 4x4 with Aisin and 3. 73)Just talked with my son after he completed a 1000 mile round trip. 1/2 of which was pulling a 07 3500 QC4x4 on a float. Return trip truck only,
He commented that he was VERY happy that he did NOT get talked into 3. 42 gears and found the 3. 73 to be perfect for our roads (usually 70mph on 4lane and 55 or so on two lane. )

Ran 11 usmpg @ 70mph pulling approx 10000-11000lbs. Running empty, got 18USMPG on return trip. (all hand calculated)
First regen at 2000miles... ..... evic said " exhaust system regen in process. Exh filter 70% full" took only 5 min to regen to 0%.

His 11 Dmax reg approx once per tank of fuel.
