It looks like AAM makes 5.13 rears.

I looked at RRP's sight and they don't show all of the options anymore. Are 5.13's still available?
I noticed I couldn’t find Yukon 5:13’s now either. WTH

:angry:

I might just need to buy gears and put them on the self since this stuff seems to randomly pop up and then disappear.

4.88 at least has been consistent in n availablity...

East Coast gear supply supplied my AAM 4.88 Rear 3 years ago. I posted my receipt if you search with every part number that will be required including that newer seal that these rear axles require.

Not a new Gen but...

Weakest link in the chain kinda thing. One thing leads to another........you might know the song. Seems like a re-gear on a 4th Gen or later, means a re-program of shift points is mandatory-if you tow. Seems like a 100 yrs ago now but a long, long time ago, on a forum far far away..........there was a guy (screen named Crash) with the same truck as mine (3rd Gen w/G-56). He went to 37's & said it felt like it was meant to be. Said it no longer felt geared like a farm tractor. But he did not tow either. It just seems natural (with all the new technology that is already in them) to be able to have the dealer be able to sit down with the owner & custom program their truck for what they do with it. Send it with a general program but be able to do more if needed. But what do i know.
In WNY State. 2008 Red QC PW G56. No lift yet, stock size tires. It pulls an 18' 2016 Starcraft AR One Extreme, 3500 lbs.
Load Pro 35 helper springs. 2015 A.R.E. MX Series custom cap. PCP front diff cover protector. Mag-Hytec 6 qt rear diff cover. K&N replacement air filter only. Dual grounded throttle body. Winch TPC bypass. Fab Four rear bumper. DURA BAK lined rocker protection. And a bunch of new front end stuff.

G-56 Gear ratios: 1st) 6.29:1 2nd) 3.48:1 3rd) 2.10:1 4th) 1.38:1 5th) 1.0:1 6th) 0.79:1 Rev 6.29:1 --- = 78.01613:1 Crawl Ratio
-------------------------5.94:1--------3.28:1-------1.98:1-------1.31:1-------1.0:1-------0.74:1-----5.42:1 ---- = 73.675:1
545RFE----------------3.0:1---------1.67:1--------1.0:1--------0.75:1-------0.67:1------------------3.0:1 -------=37.21:1

2013+ 32.47 crawl ratio...............Can you see the trend ??????????????

You're a dude posting on a forum who is competent. The general public is stupid. They have to consider warranty, cost, the basic premise that people don't know what they want. Also, DO YOU REALLY TRUST A STEALERSHIP???? Custom tuning has gotten more difficult over the years too. I think it's two-fold, one they don't want people screwing it up and trying to pull warranty claims. And second, they want to help drive repair business to their dealership networks.

Hell, I used to adjust the fuel/air tables myself with a serial cable on my Trans Am, it was easy to do. There was even free software to do it.

ProCal can handle regearing, but I don't really know what it does within our system.

Just so you're aware for the future, the ProCal tunes the TIPM which is the fusebox essentially but handles certain functions like the speedometer. It adjusts what the speedo sees from the wheel speed sensors which adjusts the tranny and throttle

Something like a diablosport may acheive the same function but on the other side of the connection, where the pcm gets the normal signal but modifies its reaction to it

FIND A RACE shop to do this, they do it all the time, don't be cheap and try this yourself unless you have a LOT of automotive experience, the exact right tools, and are really precise in your measurements and work...it's just not worth it. The install took the shop in Ohio around 8 hrs+ to do both, and that's all they do is hot rod cars and rear ends. The $800 for a competent install is SOOOOO worth it if you're only going to ever do this once, I beseech you to pay someone to do this job.
Thank you, good info. I'll give Randys R&P a call to see what the kit is going to run.

Edit, I just called Randys and they claim that they do not have 4.88s that fit the 2014+ Front 9.25. Allegedly they are working on something but don't currently have it. I also called Yukon and they confirmed, nothing they currently have fits the 2014+ front 9.25.

So are there any other options besides Nitro?

Uhhhhhhh, excsqueeze me? :shock: i called, told them my truck, told them the part numbers I found on their site, the tech confirmed they’d fit, gave my credit card #, done. Wonder what’s the issue?

As far as I can tell, all your costs seem to be significantly less. You got the parts for WAAAAAY cheaper than their current market availability, and if you paid $800 per axle then you also found the cheapest labor costs for axles I've ever seen. As most cheap places charge around 1200 per axle.
Standard rate that I've found is $2500 for parts and labor for the entire job.
^^ Way more than I paid

Although I might install mine myself. I learned a valuable lesson once about thinking I could get away with not torquing down roller rockers on the valve train properly. Costly mistake. It's the whole .005 inch stuff with setting preload and backlash, the superfine measurements required that make me personally nervous about doing a gear swap myself. I have a tendency to not be highly detail oriented. Last thing I want to do is blow apart my rear end because I looked at the dial once and said good enough. Although I'm a little older now. ¯\_(ツ)_/¯
I know quite a few top notch auto/truck mechanics. All of them have told me that they wouldn't do their own re-gearing - they would find a shop that specializes in re-gearing AND has a well known reputation...

The transmission is your weak point when towing. Keeping it in the correct gear for as long as possible is what keeps temperatures down i.e. the torque converter locked on a gear consistently for as long as possible. I can say with 100% unwavering confidence that 37” tires on a 2015 Ram power Wagon, and towing is best done with 4.88 R&P front and rear along with the AEV procal adjusted correctly. Also you must mind your gear shifter, and stay on top of your transmission by purposely downshifting to lower gears. The above mentioned set-up allows you to climb most grades in 3rd gear with low temps, as long as you shift back down when ever the truck tries to go to fourth. On harder climbs you go to second gear with a load. This is mainly about discipline, and not letting your transmission sneak into higher gears and run up the temps.

My gearing was done by 4x4 Land in Topeka Kansas. They were excellent, and got everything perfect the first time. They know Rams, and install a lot of AEV parts. 4x4land.com
2015 RAM Tradesman PW: White Knuckle Sliders, FAB FOURS premium bumpers front and rear, Magnaflow #19200 exhaust. K&N cold air intake.

Tires: 37x12.5R17 Toyo Open Country R/T, mounted on AEV 8.5" wide Katla wheels. Corrected Ring and Pinion gears: 4.88 Yukon (front), and 4.88 AAM (rear). AEV differential covers (front + rear). Thuren XHD swaybar endlinks.

Not sure about the new Gens but 3rd Gen auto trans guys would install a larger trans oil cooler. I did it on our 04' Reg Ram 2500 QC. 12 row to a 24 row. That worked great. If I had an auto, I would do the same. I always think this: Going up Ike Gauntlet on a 100* day...would I overheat ? If the answer is maybe, then install a larger trans cooler. I also had an engine oil cooler on our 04'. It towed 10,500 lbs. No issues with overheating when towing, even with my foot literally to the carpet for 10-20 min when pulling a 6* loooong hill in Ky/Tn. It was in 2nd gear @ 45-5500 rpms the whole time.
In WNY State. 2008 Red QC PW G56. No lift yet, stock size tires. It pulls an 18' 2016 Starcraft AR One Extreme, 3500 lbs.
Load Pro 35 helper springs. 2015 A.R.E. MX Series custom cap. PCP front diff cover protector. Mag-Hytec 6 qt rear diff cover. K&N replacement air filter only. Dual grounded throttle body. Winch TPC bypass. Fab Four rear bumper. DURA BAK lined rocker protection. And a bunch of new front end stuff.

G-56 Gear ratios: 1st) 6.29:1 2nd) 3.48:1 3rd) 2.10:1 4th) 1.38:1 5th) 1.0:1 6th) 0.79:1 Rev 6.29:1 --- = 78.01613:1 Crawl Ratio

It takes a lot to heat the trans on the 10+ trucks. We were grossing a touch over 15,000lbs towing up the hills of Napa area in 2nd Gear almost pinned. 4,000rpm+ for a few hours. Trans temp didn’t go above 175, engine oil temp was 240, coolant was 219 and holding due to the electric fan.

I do not consider the Eisenhower Grade to be a serious Tow. It’s not that steep and it’s a very short hill. There are a lot of other rows that are much harder due to the duration of the grade.

I have towed our 8000 pound travel trailer around quite a bit with my PW. Never seen the trans temp rise over 178 degree's, and I typically only look when I am on long/steep grades when the truck is screaming at red line for a while. There certainly is no issue with trans cooling on the newer trucks.

Give $1500 to a mechanic or spend $1500 on tools and do it myself? Tough call.

It was, iirc, $2200 in parts and shipping when the front diff ring gear grenaded and took out a locker in the process in Moab. The owner who fixed that in an open field suggested using Yukon

Depends on the shop's honesty wouldn't it? "You didn't follow the break-in procedure" Lot's of horror stories out there. But I'm cynical coming from the car scene where a performance shop would fuck up and then blame the customer.

I think thats exactly his point on making it a DIY project. Ask Cactus Red on how much of a pain in the ass it is (he had a ring hear bolt fall off).

I, personally, think my balls are a bit too small to attempt to tackle a DIY project like that. Would love to have the knowledge and experience, though!

I've done Dana 60's and 70's which are much harder to do because it's all adjusted with shims. At least the AAM axles have spanner nut adjustment on the carrier bearings, that's half the battle. GM 14 bolt and Ford 9" are the easiest.
Every mechanical discipline incorporates a margin of error, just work within that margin and you'll be fine. It's not rocket surgery, I say go for it! :ugeek:
