2021 Tradesman Locker options?

Yea, I'm pretty sure the lower payload is due to the softer springs.
32 spline shafts are stronger than 30 spline.

I thought they were slightly different hence the reduced axle ratings but that could be ram compensating for the suspention

Rear GAWR is 6200lbs on the PW. It’s the suspension that is limiting not the axle itself.

Eh. Dunno whats up eith the rating but here>>

Ah my bad i mixed them up i was thinking it was the rear that was lower but its the front by a lot

There is so much bad information in this thread it’s mind numbing.

I was just trying to research if anyone had ever out a g80 in a ram HD truck before.

I call the G80 a LSD as well. I realize its not, but its a horror show. I would either have a basic LSD or selectable locker. Don't waste money on something cheap, clunky and jerky like that. They do not perform very well at all. Just flip the switch on a real locker and crawl on. The Power Wagon set up is obviously king. But I feel like its LSD should be a bit tighter.

G80 is LSD not a locker has never been a locker and never will be a locker. That being said if you want to put one in a Ram with 11.5 rear axle you will need to use a GM carrier and remachine the whole housing to accept the GM carrier…. This can not be done nor is it worth 1 minute of the work required

Detroit Locker is …a locker. It is either on or off, sending 50% of torque to each wheel. A torsen-type LSD resists speed differences in the output shafts, but does not fully lock the two sides together. A torsen-type LSD is very smooth, linear engagement. You won’t be able to feel it.

You may be thinking of the Detroit Truetrac which is just a torsen-type LSD

A true locker does not guaranty 50/50 torque split, that is what an open diff does! A locker makes it possible to send 100% of the torque to the wheel with traction (like when the other wheel is in the air, it takes zero torque to spin). Most clutch-type limited slip differentials can't send 100% torque to the wheel with traction in a high-torque situation, such as one tire between a rock and hard place and the other in the air...

By the way, my Ram's limited slip 'anti-spin' differentials works OK, combined with the ABS traction controls. I would prefer an e-locker, where I could select it and thus ensure both rear tires spin at the exact same rate, regardless of traction difference side to side.

Dont think thats right. G80 is a clutch engaged automatic locker. It has no slip limiting like the ram with one tire moving a bit faster than the other. The g80s, like my 05 Silverado and 2022 senses slip and locks both wheels together.
" The G80 is a mechanically activated automatically locking differential. When the wheel speed of one rear wheel exceeds a certain ratio (compared to the other), it will automatically engage. However, when you exceed a vehicle speed of about 25 mph, it will automatically disengage.' -google

@johanh13 sort of right on the locker part. With one wheel on the ground and one in the are the axle will obviously spin both tires the same speed meaning torque would be 100% to the traction side.
Open dif will not do 50/50 in fact it will do 100% to the one in the air. And is completely useless and should be avoided.
Limited slips like new rams are odd and have different slip ratios for every different limited slip. Basically it spins the tire with traction something like 1/3 the speed of the one in the air. I think it's crap. G80 clutch auto lockers are the way to go, (i have all 3) they work amazing, just don't slam the gas until you feel it engage, use your head.

 

[WildBill138]

Anyway, anyone know the answer to my original question? Do they make a Yukon or Eaton auto locker for the aam 11.5? Or is it just for the 8.6?

Witch By definition is a LIMITED SLIP! A “LOCKER” locks both axles together 100% of the time when engaged in all situations such as a selectable E locker or air locker. Or a full spool/ welded Diff which is 100% engaged all the time. Take any of those 4 and drive down the road with the system engaged and take a corner the outer wheel on the corner will squeal/ break traction a G80 wont because it allows slip.

The G80 will not engage until one axle is 120RPM faster than the other.

Just like “lunchbox” lockers are not true lockers either as they allow a difference in RPM to a certain point.

There’s (confusingly) more than one type of G80. The G80 in old Camaros and such was a limited slip. The G80 in modern trucks is an automatic locker. It’s open until a certain difference in wheel spin, and then it’s locked solid. There’s no slipping at all, therefore it can’t be a limited slip.

A limited slip increases holding force the higher the speed differential. It allows “slip” a limited amount, until some preset pressure is reached when no more slip is allowed.
