Anybody build a driveline protection solution that works?

I understand the 19 won’t take existing rear covers but I haven’t tried them. I don’t know about axle shafts. I’ve tried finding info on gears and bearings but haven’t had any feedback saying heard the same as previous years. There’s a high probability they are, but it isn’t confirmed.

[cb1987]

All 2500/3500 trucks have the changes underneath. Power wagons aren’t special variants.

New front axle casting, new rear axle casting, larger rear axle tubes, different diff cover patterns (existing diff guards won’t fit the new trucks), new transfer case, new Rzeppa front driveshaft, new rear driveshaft with dual dampers, new rear LSD system on the non-PW’s (I haven’t been able to confirm with any new PW owners of that system has changed as well). New radius arms on non-PW’s. I believe the standard 2500 now has new rear dual-rate coil springs.

I don't think that the diff cover pattern changed. I have diff guards on my 2019...

After looking again I believe the front axle is entirely the same or has only a small change to CAD.

The rear axle is definitely different.

Do you know what else changed on the Power Wagon rear axle? I have read about the possibility of a 34 spline pinion. I want swap out my gears to 4.56 when I get 37s. Trying to figure out if this is even possible. I changed the fluid in my 2019 rear diff and it used the same gasket part number as the previous AAM 11.5" axles.

yes i would like to hear what these differences in the rear axle are as well ? externaly the housings look nearly identical to me. the non pw trucks have a new housing so maybe people are just confused about what theyre talking about

have your local dealer look up part numbers for the '17/'19 pw gearsets. if theyre different it might indicate a change in splines but honestly the axle and all its components are far stronger than what they need to be so it would make no logical sense to change things.

do plenty of research before hand . personally i dont feel 4.56 is nearly enough of a change when going to 37s. 5.13 is the only one i would consider but thats just me

I have looked at the parts for the 2019 PW rear axle in depth on Tech Authority. Everything points to it being the same internal parts. The cover appears to be the same while the bolt pattern is the same. As I mentioned it took the same gasket as previous year 11.5" axles. It is weird because it lists the ring and pinion as discontinued. The differential is the same as previous years along with pinion nut, pinion seal, bearings, etc. With that said the complete rear axle assembly is a different part number.

I think part of the confusion is due to the new 12" rear axle that is coming in 3500 HO single rear wheel trucks. This has a 34 spline pinion and a 16 bolt ring gear.

I have really gone back and forth on 4.56 versus 5.13. I have been comparing highway RPMs and the 6-speed versus 8-speed ratios. Currently I do a decent amount of highway driving but that will change when I get a commuting car in a year or so. After towing my UTV over passes it does feel like it could already use some lower gears.

that 12' new rear housing is also used in the 2500 cummins as ive seen them at the local dealer

That may be the updated 11.5" axle. Everything I have read says the SRW 12" axle only comes with the Cummins HO engine which is only available in 3500's.

[DamageWagon]

My 19’ 2500 has a different axle than previous years. I don’t know why they would change every trucks axle except the power wagon? Is that the case? The new 11.5 axle is visually different.

[cb1987]

some of what they do makes little sense. parts of the front axle housing is specific to pw. the pumpkin and passenger side connecting tube. why would they go to this trouble and not standardise axles across the board. pw doesnt need 6k lb rated axle but why spend the additional time, money and resources making short run specific components. it doesnt make a dam bit of sense to me.

go to any dealer and youll see pw uses what appears to be the same axxles it always has used

[Bill2014]

The Power Wagon rims and tires pair up to over 6k lbs capacity - the front axle which has a "Gross Axle Wt Rating" of 4700 pounds is the weakest link!

[cb1987]

the lower gawr in the front is because the soft springs. i suspect the rating of the axle itself is 5000 or possibly 5500. it could use a 7000 lb axle but would still be limited to less than 5000 because the springs

PW axles are actually the same or higher rated than non-PW axles. Front is 5700 and rear is 6300 if I remember right.

Here are the Power Wagon specs that I printed when I ordered my 2014:

Keep in mind that the Engineers run the suspension/chassis parts through an FEM analysis and then apply a generous safety factor for mass production vehicles - Perhaps the Safety Factor could be 3X Shock load would be the primary killer for an axle...

Well that's not what the preview looked like - but all the info did make it into the post

That's odd. That doesn't seem right. Not arguing, but apparently RAM can't even get their own info right. This is their PDF off their site for towing.

I'd been going off this forever and thought I was over my gross front axle weight all the time.

[OffroadTreks]

Well, this is my door. This is all the matters.

Zak you might wanna go look at your door again.

I know from my cat scale receipts that when the family is loaded, I'm over my front GAWR all the time. But I do have a truss.

[DamageWagon]

I have a 2019 PW parked next to a 2019 2500 Cummins. The Cummins has an all new rear axle. The PW has what appears to be the same axle as the previous years. I have not checked the fronts.

[cb1987]

going back to 2014 ,some pieces of the front housing are different from pw and non pw. some of the internals are the same but whether all internals are the same i dont know

[Allgonoshow]

I've never had failures from custom High Angle Driveline made driveshafts. He's made them for my last 3 builds including the most recent 900hp 4door short bed 02 Lb7 duramax sas'd on 43's with 1/4" steel full belly skids that I tried to kill for a couple year's before the ex wife needed gone so I traded the truck to the lawyer to get rid of her lol... I broke input and output shafts off that Allison and chromolly axle shafts f&r but never hurt the HAD drivelines, not even on the rocks. There wasn't much paint left on them or anything under there.
