[ultimate97TJ]

pros and cons....

just trying to get a idea of who has ran what and which might be better for my set up...

thanks

Both are good companies. Id try to pony up for the 3 speed verisons. I don't run one personally but Ive heard nothing but good things about each of them for what my opinion is worth. Unless somebody comes on with some specific examples I would say get what suits your project the best in terms of gearing, options and cost.

I run a stak 3speed, 3:1 & 5.4:1 low ranges. It works good. I've had it for about 2 years still little hard shifting, leaks a little. I think either one is a good choice, atlas has been around so there seems to be less issues, but stak for the money is good product.

I have the atlas 4speed. Installed early this summer. Used it alot and have had no issues at all. Shifts great. 3.8,2.72 and 10.3 to 1.

what trans do you have?

[ultimate97TJ]

i believe its the 48RH... 5.2 grand cherokee...

im still learning about the driveline as i go with my project... and i have narrowed it down to a stak or atlas for the t-case and just trying to get some input on what people are happy with...

im more looking at the atlas II 3.8:1 but i want to hear what people have to say for stak... from what i hear its just about the same thing just a little cheaper...

thanks for all the input so far... keep it coming...

I run a twin-stick Atlas II, GM 700R4, HESCO 4.7 stroker. The Atlas has been run hard and only maintenance so far is replacing a tailshaft seal. Either one is a good choice, maybe it will come down to price.

The STaK Monster box is huge. About an inch larger in all dimensions than the Atlas. If you can afford it the 3 spd is the way to go with an auto. Other than shifters that are cantankerous and a few seeping leaks the STaK is bullet proof.

i have a stak, and i really like it. the guys at stak are great people to deal with.

Have you seen the new Stak Mini Monster? It's smaller than the original Monster box and available in a 2 speed and 3 speed.

The AtlasII & 4 speed have synchros wich allow it to shift on the fly.
In 2.0/1 low range I can shift to high range @ 40+ MPH.
In 4.3/1 I shift to high @ 20 MPH
Put the trans in neutral and shift the case from low to high.

Atlas has been great to work with and they have the ancillary stuff needed to finish the job if you have non-typical installation issues. (Weird adapters, shifters, etc.) Their tech line is super.

I'd have to agree with the atlas people on this. I've been running the 4.3 since the spring of 2003 and have never had a problem. The mileage on the case is around 50000.

With a 5.2 and automatic, you would be fine with an Atlas II. V-8 torque and proper axle ratios will give you decent crawling power. I run an Atlas II 3.0 in my xj with 4.56 gears and an auto and never lack for power. If you go too low in your tc ratio, you'll find that when you need wheel speed it's not there.

atlas is looking like the way ill go with my project...

thanks

X2 ~ this is a great feature. plus, if you didnt already know, if you disengage the rear diff on the fly and run front wheel drive only you'd be amazed at how the front wheels will drag you over and through ruts that you just can t make with the rear diff engaged... then on the fly you re-engage the rear diff. unless you have rear steer it like the rear wheels just want to go straight instead of following the front wheels... anybody else ever try front diff only on hard lines ?

awesome..
and thank you im ordering my atlas in 3weeks and starting my build asap..

thanks again for the input and help

Ditto. I just finished putting an Atlas 2-spd 4.3 in my 98 TJ. Luv it so far, but don't expect to install it in an afternoon. I had to modify my skid plate and get a shorter front d/s and a longer rear d/s.

I started out planning on buying a STak, but I couldn't get them to answer an email, so I bought an Atlas.
