NV3550 that was rebuilt a couple years ago, but has less than 100 miles on it.
Attachment 505

Stak Test fitted to NV3550
Out of curiosity I weighed these. Stak weighed in at 130 lbs, NV3550 with bellhousing weighed in at 105 lbs.
Attachment 504

Transmission and Stak are installed except for the shifters for the Stak. Everything went fairly well after I figured out how I wanted it clocked. Case is big and has eliminated my plans to run a flat skid for now.
Stak came in missing the calipers for the pinion brake, so I need to call on that today

Installed Stak

High Pinon Dana 44 (HPD44) front out of a 1978-1979 Ford F-250.

I need to grind part of the perch to fit ubolts on correctly as you can see in pics. It is just mocked up and u-bolts just finger tight.

Rear Axle
 

D60 out of a 1978-1979 Ford F-250 or F-350

This was a pretty easy swap. Stock perches need to be ground off and new ones welded on to fit Jeep application. Pinion angle needs to be set according to angle of transfer case and type of driveshaft running.

Suspension
 

With the axle swap I am converting to a Spring Over Axle (SOA) setup.

Rear - I used two main leafs from a superlift 1.5" replacement spring pack with the smaller leafs from the stock springs

Attachment 561

Front - I used stock YJ packs but I took a main leaf from another pack and cut the eyes off and added it below the main leaf

Nice info. Where do you plan on wheeling in 2008?

Badlands, Windrock, and Lost Valley are definites. Possibly Hillznhollarz or Redbird and whatever else comes up. Wouldn't mine going back to Harlan and BigRock(NOW CLOSED) as well, but that would probably be pushing it.

I plan to continue adding details, pics, and any other details as I get things done.

Left message with Stak this morning before they were open and they promptly called me back and are shipping the missing caliper. The good customer service I have heard about is holding true!

Stak came thru with the missing caliper bracket a couple days after the call.

Ordered (4) 38x12.5x16.5 TSLs today.

Attachment 529

Haven't really done anything to it lately.

Progress is slow, but getting a lot of small things done. H1 Runflats are cut of and beadlock ring is ground smooth. Sandblasted and painted front axle hub and steering arm parts. Should be able to get the front axle put together quickly and permanently installed.

Attachment 562

If you dont already have plans for it, add some type of support at the back of the Stak. I have a 3 speed Stak in my MJ and at first it scared me just having the Stak hanging off the back of the tranny but after talking to them and getting something to help support it, I feel better. Also theres no way to get a flat belly with out a super tall body lift or hacking the crap out of the tub. I chose to hack the crap out of my body to get a semi flat skid :D Looks good by the way :cool:

AARON

Thanks,

Yeah, I would feel better with a support on the Stak and will do eventually. I just want to get in moving again first. I quickly realized the flat skid wasn't going to happen without some tub changes, which I will probably save for a future project if ever.

I hear ya. Do you think you will have any issues with front driveshaft lenght and angles? I cut and rotated the knuckles on my HP 44 when I cut it down but that was with 4" of lift and the NP 231. Now with 6" springs up front and the Stak, my front d-shaft is super short and I am not sure I can get the shaft to run at speed with out destroying the CV or having wicked vibes. I would like to see your thoughts on front a driveshaft.

AARON

I am hoping I can run a standard driveshaft in front. Running a CV on rear.

Checked the driveshaft. Front pinion is up at about 5 degrees, Stak is up at about 3 degress. Driveshaft is at 10 degree and will be about 37 inches and drop 7.5 inches from pinion to case. I think it will be ok running a stock driveshaft.

Anyone more knowledgable, please chime in. I can probably get the Stak close to level (0 degrees) if I need to

Pics of my little Jeepers, Well I'm not sure the littlest is quite ready!

Wish I could keep my Jeep in the living room, I would be able to get it done faster :)

Very nice write up.

Sounds like you will be fine on the front. I keep forgetting the layout between a YJ and an MJ are that different. Keep up the pictures!

AARON

Just thought I would update on progress. The project is still underway, but progress has been slow. I was able to get the last three H1 wheels sandblasted over the weekend. Should have them painted and mounted up this week. Mostly been waiting for my inner Chromoly shafts, when I originally ordered them, I got F-150 instead of F-250 and there was some length differences. Just got a tracking number and I should have them Thursday (Happy Valentines Day to Me). I plan to have the front end together this weekend and have it on all fours. Will post up pictures when I get the treads mounted up and rolling.

you can make your own rear stak support, or buy theirs... it's super nice, notched to slide to any angle etc...

http://www.complete4x4.com/ImageFoli...6buggy_216.jpg

all looking good by the way...

How bad will this handle hills with 38s and a stock wheelbase? I will push the front forward an inch and the rear backword and inch, but I doubt that will do much. Might be able to get 2 inches out of the front. Is it worth trying to get the extra inch.

I would definitely support the stak case and keep the stock trans mount also. I would hate to break the stak off of the tranny! Minimize your driveshaft angle and your u-joints will thank you later on!
