So, to anyone else who has blown the shiznit out of their G-80

What have you replaced it with?

Another G-80?

Or

A Torsen (TORque SENsing ) unit?



It is time to redo mine.

Thanks.
Juice.


BTW new flexplates (when you guys get some decent power lol are only 169.00 CDN so don't pay too much!)

I think Juice is admitting to "blowing it out of his asse." http://www.dieselplace.com/forum/images/smilies/hihi.gif

Were at 800 + and the stock flex plate is working fine, so why replace it? Now that's with lots of drugs with a stock turbo so maybe them new fangled twins cause it to break where the drugs don't.):h

Finally ):h

Are TorSens even avaiable for these powertrains? I was kinda' leaning toward the Eaton electrically operated diff. $$$!

There are no aftermarket solutions yet.

I am going to rebuild the broken parts on the G80 for now, until something better comes along.

While the Torsen is a great AutoX/RR diff, I don't believe they make a model for our trucks. And it is NOT a desireable drag rear, there are better. It doesn't lock up. Ever. Both tires spin at different RPM. If you have a Camaro, go with the Torsen for RR/AX, but if you're dragging? Nope. It causes the ass to kick to the side on launch. Been there, done that, and have the pic of getting too close to the wall for my taste.

What i can't get an answer for is that Dodge is using a similar AAM and a TORSEN..... will they not swap directly?

Pat, IIRC the TORSEN system can be custom ordered to whatever 'Bias' you want as far as power transfer.

4:1. 6:1 3:1 or ???

At least as per their website.

I like the idea of gears over clutches as well.... mind you, if you pop one, you might as well kiss your @ss (rearend) goodbye):h

Don't get me wrong, the Torsen is about the best affordable rear for a 2wd hipo car in the twisties IMO. Putting the T2R version in my car knocked nearly a second off my laps times over a Auburn friction style. More control, more power to the ground.

But on hard launch it forces the rear to the side just like a one-legger. It is a major the reason so many Fbody GM's go into the wall with inexperienced drivers IMO.

For truck app's, a locker is the most "utilitarian" system. When you get a 7000lb truck stuck, a friction or geared-bias style won't have the low RPM grip at both tires like a locker.

Is the Elocker any beefer?

Elocker isn't available for the rear axle

I did my annual front and rear diff fluid change and the G80 looked great upon inspection. But I only drive my truck to the grocery store on Sundays if the weather is nice so it doesn't see much abuse :D

Is your grocery store at the track?

The Dodge unit will swap in directly. Lemme know if you actually get a PN, I tried to order one from the local Dodge dealer and they said they required a VIN to order it. :rolleyes:

I think I am going to hold out for a Detroit or Powertrax locker. I have emailed both companies and they both say they are working on it. If more DP members generate some buzz they might speed things up.

BMDMAX,

How about posting the E-mail addresses and we will hit them with all 10,000+ members. :D

So in your opinion Brandon, what would be the best compromise for 1/4 mile runs and a DD/ Hotshot rig?

TORSEN/DETROIT/POWERTRAX ?

A Spool is out of the question for a Daily Driver.

Not an easy call. It depends on what quirks you are willing to live with.

Me, I am most likely going with a Detroit. I think it is the toughest and I am willing to live with the occasional backlash, chatter, etc. I want balls out track performance. I would imaging dealing with winter weather this would not be a good option for you since it is locked up until you turn. They can get squirelly quick on a slick road with a stab of the go pedal.

The Powertrax units claim the best of both worlds. Seamless operation with full lockup. I have heard of them blowing apart just on gassers though, I don't know if they can handle the abuse of the diesel torque or not. It looks like a nice unit and is reasonably priced.

The Torsen is a pretty slick concept. It probably would give you a good split of performance when you need it and make a good daily tow rig. I have heard of a few grenading on the CTD side of the house too. There are plenty of third gens pushing 900 foot pounds through them already, we just need to see their lifespans.

One thing that can help if you are putting in a new diff:

Open it up and look carefully at the components. If you see casting flaws (voids, bubbles, foreign matter imbedded) in critical areas, get another one. It's more common than you think. I went through 3 Torsens before I accepted one. Next, put a .030" radius on all sharp edges of stressed components. This can make the assembly up to twice as strong as a OEM part. Be sure to throughly clean off parts, as magnetized particles won't rinse off. Cryo treatment is said to help, and it never hurts (except your wallet) to magniflux critical parts. Realistically though, just a couple of hours with a Dremel will make the unit significantly stronger.

I only drive my truck to the grocery store on Sundays if the weather is nice. :D
Yeah, for a dozen cases of the big cans of whoopa$$ ):h

The Dodge OEM diff is available from Randy' Ring and Pinion.They list it as a L/S not a Torsen. Might want to call them to verify. I'm holding out for a Detroit myself.

AAM's Site lists the dodge part as oem and TORSEN

Torsen is a limited slip that varies torque bias to the wheel with traction.

In some cases it is superior to a locker. as with anything there are tradeoffs though, and hopfully some input before i upgrade mine.

How do your dodge pals like em? Are they grenading them? Many new dodges running 1k torque and running em at the strip?

When you put the truck in the air in park, and turn one tire, the other will rotate in the opposite direction freely, if it's like the 2 other model Torsen's I've used. Freaks some people out, as limited slip and lockers normally won't turn freely.

The posi effect increases (or so it seemed to me) as a function of power, but it never locks. It will do 2 wheel burnouts, but the tires will typically spin at different speeds. They also have an interesting rattle to them sometimes, it doesn't hurt. Sounds like dice in a cup I guess. Parts inside are worm gear looking rods, and I think the play in them causes it. I had 2 bad castings in a row, and contacted Torsen directly about it, they were very helpful, and helped me in getting a good one. Casting voids in the root area of the ring gear flange.

I know your expereince is with a rwd but do you think a 4wd would suffer the walking?

Probably not if you were in 4WD as the front is doing most the work it seems, and traction isn't as critical. The "walking" is just indicative of the fact it's not supplying the power equally to the tires. So it has less traction than a locker.

Its like when you hang the hoops hard and one tire hits a slick spot:eek: Something a wish to avoid;) I dont want my sh!t pointing at a wall! Just wondering if the 4x4 would keep its tendancy to sometimes get squirly in check. I was thinking it would but.....

Thanks for the insight. I dont care what Mike said about you, you vette guys are alright:D

Is there something wrong with my rear then? I can't get both tires to spin no matter what, not that I try to do burnouts, but whenever I loose rear tire traction (often), my pass side tire spins away, no help from drivers side....

Look at the sticker in your glovebox for a G80 code on the build list.

No G80 = Open differential.

If you ordered the truck with the HEavy Duty Power Package, you get it. If not, you must specify G80 as an option you want.

I do have the G80, made sure of that..

Hmm.. The G80 works a little different than most rears. It only locks up to a certain wheel RPM then releases. When I do burnouts, it normally leaves two black stains.

...... Hey Juice? Er, Got Tubbed? .....just an Idea.

It depends.....sometimes it will spin one sometimes not. At a dead stop though if I light up both tires it will spin them both. If I nail it from low speeds I will light up both. This is going straight. I try no to gas it around corners.

The search for limited-slip options for the new Dodges has been talked about a few times on the Dodge boards. I definitely could be wrong, but I was under the impression that GM and Dodge rear ends had slight differences (even though both AAM 14 bolts) and the parts were not interchangeable. Like, as far as I know there are still no aftermarket limited-slip/locker options for the Dodge models but there are for GM's. I would definitely consult with someone from Randy's RIng and Pinion to see if the Torsen will work in your truck.
