Dana 44 Swap

[Nakashige]

I think I remember reading in steves build he thought a 44 would require less lift based on size of the housing. Its going to be interesting might have to do a rear d44 on leaf as well?

[chevycrew]

I would not run a rear 44, it won't hold up. Try a semi-float 14 bolt in 6 lug flavor, ebay a take out e-locker. Front, use the F-250 housing with chevy knuckles out. Axles will be 67" wide. (I originally built my wifes truck this way, ill get a link to the build) With the stock oil pan ill guess 10" of lift over stock. While the 44 housing is smaller, its also more centered.

Steve so I take it I am going to have to do something with my rear to get it to balance out right. Will I need to do leaf rear and will a stock transfer case match up with a 14 bolt semi float. What about a 10 bolt front.

[HARDTRAILZ]

The SS rear is a 14 bolt semi float. Mine works great.

[Nakashige]

What is in the back of the Tahoe and 1500 series trucks. Hardtrailz are you still running spacers on your rear?

[HARDTRAILZ]

Yep. Still need adapters since the SS have same 6x5 pattern

[chevycrew]

The stock t-case needs ditched when going solid axle. Tahoes have a 10 bolt rear, but they are weak.

[Nakashige]

I remember there being talk About using the stock t case with a d44 in the front and stock rear. You used a np241c correct and that mated up with our tranny fine right

[chevycrew]

An s10 blazer or truck 27 spline np231 case is the one you want, find a early one with the fixed front output. This case will bolt to the stock trans and adapter. This is what anton is running.

[Nakashige]

NP231c Correct? Steve the main reason I am going with the D44 is to stay street legal and 35s

[v7guy]

What's the problem with the stock transfer case?

[Nakashige]

It Prob has something to do with the front disconnect and how our 4x4 engages. Said and done i was going to do sfa and its now turned into a full sas and keep the truck street legal in a state that hate off roading and modified cars and trucks

What's the problem with the stock transfer case?

Stupid clutches. Needed for the nutty A4WD mode, but don't offer a true 100% lockup when fully engaged in 4HI. Also no aftermarket support, which I found when I called around to see if anybody had gears to make a 4-to-1 low range. The NP231 normally comes with the same 2.7-to-1 as ours, but you can get that fixed easily.

[dirty anton]

np231c with sye while at it. i agree with donny and would do 4.88s. think they would do well with 35s. wouldnt measure out the drive shafts till truck is sitting on all 4 tires. this project can easily be if not prepared! should turn out awesome tho.

[fishsticks]

Front DS could be cut/lengthened/reyoked if you HAVE to stay with the stock tcase for now. Its total in/out travel is pretty shitty though. Maybe cut the CV off and find a long spline DS of some sort.

Rear uses a standard u joint size if you need a longer replacement. You will need longer control arms/springs unless you're converting to leafs.

[chevycrew]

The stock t-case won't allow enough angle where the front shaft slides in.

[Nakashige]

Steve, Mike, Don recommendation for rear 14 Semi float from a ss and keep the rear set up as is or go Leaf and go 14 bolt semi float from a chevy truck?

[Nakashige]

sitting down to discuss with fab guy in the morning. 6 or 8 bolt? He thinks he can get it done in 2 weeks from when we start and have parts. Need to keep it street legal as well

[chevycrew]

6 on 5 1/2 pattern, chevy outers on a f-150 or f-250 housing, rear run the sf14 from a early 90s chevy truck in 6 lug. I think to get the lift in the rear no matter what you will be redesigning the rear suspension.

[Nakashige]

ok going leaf then would be the cheapest correct found my rear axle at least from a 91
