I seem to be having trouble finding this information that is in the back of my head.

Can a C4 Dana 44 use Jeep "Super 44" gears? I remember reading that it was only the Super 44 ring and pinion from the rear diff that you could use in a C4 D44. I just cant find the info to confirm or deny it.

I have Jeep Super 44 3.73 gears in my car now. I bought them as pull outs from a 4WD shop in San Antonio for $100 and had a local shop install them. They work.

That’s wonderful news! I had bought a set of Super 44 4.10’s and I was trying to get my information straight before potentially wasting my time installing them.

You don’t need anything special for those gears correct? I am going to purchase a rebuild kit for the bearings and seals and wanted to also confirm I can use a rebuild kit for a Corvette Dana 44? Thanks for the reply!

The shop that installed them sourced all the other parts and told me they patterned just fine. They are really quiet and smooth. There is more exhaust noise and induction noise in the car now but the gears are fine. I don't know if he used a parts kit or got the individual parts from his supplier. He did say they fit fine with no issues. I love my T56 swap now.

Post the information off of the ring gear and also the pinon. With that info ID can be made. Very dependent on what you bought and information posted the inside of the housing will require a 'massage' to fit the larger Super 44'. A standard 'vettte/Viper is 216mm ring gear and the later is 226mm. Also make sure the ring gear uses 3/8 ring gear bolts. Later Super 44' is 7/16, Also very dependent on what info you post is the crush-sleeve used for the install. Not all require the 2" tall sent in most kits. The last couple I had used a shorter collar.

What else is in the package if you bought NEW from some vendor other than Dana/Spicer.

I currently only have the ring and pinion. I was looking into which bearing/seal kit to purchase to rebuild my 44. I'll find the gears and post the numbers.

v8vette84

On the Pinion:
DANA 2005117 KA
D4 41 10 C1L481

There is something on the other side of the pinion but I can't read it too well. Maybe... 798 526M5 (The bottom half of the letters are missing)

On the Ring gear:
3 11 08 DANA D 2007773 P4L866 41 10

That looks to be very late model and very likely has 1/2" ring gear bolts. It's a Super 44 w/226 ring gear. I've never seen/heard of anyone 'reaming' the case to accept 1/2" SAE bolts. I'd say get a 1/2-SAE bolt to confirm the ring gear is actually threaded for 1/2". It looks to likely also use a .630 crush collar. In Dana/Spicer lingo I believe it's considered Type 4.
Is there a crush-collar in the package with the gear kit? Generally speaking Dana/Spicer would supply new bolts with the package. It would be odd for them not to be I'd think.

That same pinion is used with a different ring gear for 7/16 bolts.

It's intended use would be for '07 - '11 or so JK Rubicon. Maybe you could find a buyer or trade locally. You bought from who?

See if maybe there's a local CMC/Jeep dealer with this part # 68035573AA . I believe that's likely a 1/2" SAE correct ring gear bolt.


**** I might actually have a NEW set of Dana/Spicer 4.10 Uper44 w/226 ring gear. I need to look - it would be tomorrow or Saturday before I could confirm.

I bought these used off ebay for a good deal back when I thought it just had to be gears from a super 44 to work. I just went out and checked and the ring gear requires 1/2-20 bolts.

So I can't use this ring gear correct?

v8vette84

I just wanted to upgrade to 4.10 gears and to do it on a budget. I have successfully set up a 10 bolt rear so I was planning to do the job myself.

WVZR-1

Like I mentioned - I've never seen/heard of anyone 'reaming' the carrier to accept the 1/2" bolts. Can it be done? I'm sure there's likely some that would say sure! Yours isn't apart yet - correct? If a Jeep/CMC dealer has an actual correct bolt it would be interesting to compare it to a correct 3/8 ring gear bolt. There's maybe more reasons considering they're used to buy correct new stuff to install vs using what you've got. They might be an easy sell.

Reaming the 10 bores on the carrier ain't a task for the DIY guy!

Benny42

Sorry. I didn't intend to spread incorrect info. Thanks WVZR-1 for setting it straight.

I'm not recommending it, but you can buy sleeves to use 7/16" bolts in 1/2" gears. For anything diff related I recommend raytech.com. They always have whatever I've needed. You can use a crush sleeve or a shim kit to set the pinion depth. I prefer shims, but either will work.

I bought the Mopar Viper gears, P5007043. It comes with the 3/8" bolts and a crush sleeve. It's off at the diff shop now getting worked on. I can give details on what it took to install when they finish. I paid about $200 on E-bay for them, then paid another ~$180 for the speedo correction gears from http://www.zr1specialist.com/HAT%20W...on%20Gears.htm

WVZR-1

Sleeves are use to adapt the bores on the carrier that are bored for larger hardware to a ring gear that's threaded for a smaller diameter bolt. There's sleeves for 7/16 case/carrier to 3/8 threaded ring gears and there's sleeves for 1/2 case/carrier to use 7/16 threaded ring gears. None of this is of any value to the OP. A pinion that's 'manufactured/intended' to be installed using a crush sleeve can NOT be installed using shims for the front bearing.

v8vette84

I used a spacer and shims to set the correct preload for the pinion on the 10 bolt I assembled. Is that different than using a solid spacer and shims on this 44? Replacing the crush sleeve seems to be pretty common from what I saw online. I'm not trying to say you're wrong but I'm just curious why you can't use a spacer/shims to get the preload you want? Is that specific to the 44?

Reaming the holes I'm guessing is more advanced than just drilling them out to a larger size? Is that something a machine shop is capable of? I'll have to see if I can get one the correct bolts to compare like you mentioned.

v8vette84

That's a very reasonable price for 4.10's. Even Mopar branded which means you are getting a quality gear. ( I would think anyways) Thanks for the info!

WVZR-1

I ain't going to debate what you've done in the past w/GM10 bolt.


The gear kit you have I believe is meant to be installed with a .630 collar. The last couple of them that I've needed I got from Nissan. I don't recall the # but if I have one still in the package I'll post back.

Get a correct bolt in your hands. Is your car apart OR do you have a 'vette D44 carrier already? You could take your carrier and a correct bolt to a quality machine shop and ask regarding boring/reaming the case/carrier to use the 1/2" hardware. A 10 pack of the correct bolts is cheap.

Were it me? I'd maybe try a 'local sale' of the gears and buy a correct set of NEW gears for the install.

** 5183525AA might be a correct collar for your gear kit from CMC/Jeep - confirm before a buy!

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

+++++ I'd buy a package of 10 bolts, a correct .630 collar and maybe even a new pinion nut and sell locally as a package.

Yes you can. Companies like Ratech make shim kits for pinions designed for crush sleeves.

WVZR-1

This as well as #13 by yourself is also of 'NO VALUE' to the OP.

The OP mentioned he didn't recall the info and asked for help! I believe I asked appropriate questions and actually ID'd what he has 'in hand'!!

I ain't interested in your 'yes you can' (because NOT ALL CAN) or NOT understanding the 'sleeves' that you mentioned. NEXT?
