Atlas or Stak

JeffK5 · 12-28-2009, 08:11 PM

Went big on this reincarnation of my project... I now need a transfer case.

2 speed-3 speed-4 speed?

I like the 5.44 3 speed Stak, ratios seem just right.

Two speed cases seem very limited..

Four speed seems like overkill and is big $$.

Anybody have ether and wish they didn't? Stak has both a good and bad reputation.. Bad- super noisy and pop out of 3:1
Good- super stout with no ad-on costs like Atlas cases.

And Atlas has a great history.. but costs mount when you add upgrades.

Any input?

Jeff

Considering the company behind it, I went with an Atlas. Plan "B" would have been to rebuild a 300.

With the slushbox, I'm happy with the 2-Spd.

YMMV.

I have owned 2 stak 3 speed monster boxes and think they are built tough! Mine have never whined but the 1st box in the old truggy would sometimes come out of gear in 5.4. Shifting is tough while it is new but gets better as it breaks in. I have talked to the owner a few times and really like the service and product. Only thing I have not broke wheeling is my stak. Remember a time recently when I had the motor reved up and jaming it into rear wheel while being impatient.

The mini stak may work for your application and save some $. Atlas is great too. Good luck!

I like the STAK thus far, no problems as of yet... the gearing was good on the trip you were on with me... We didnt use the 5.44 hardly at all, but then again, my axles are 6.72:1 gears, so that helps.

I haven't had any of the issues that some have spoke of with the stak... smooth sailing thus far.

I say atlas, based only on my issues with a Stak. I've never been able to get any customer service. I have the popping out of gear issue on a 2 speed 4.3:1 box. Ownership has changed, but I still can't even get a return call. The only two times I could get a hold of them was with the old owner, tried thier fixes with no luck.

Wanna buy a good used stak?

Thanks for the input guys.. This thread looks like the 30 I found on the web...a couple guys love the Stak then one guy chimes in and says it pops out of gear...it leaks...it's impossible to reach Stak tech/support.

I'm having a hard time sending $2,700 off for a crap-shoot.

I've also been having no luck getting Stak vendors to convince me why I should drop my $$ on there product... I've had a couple prominent sellers on PBB refuse to comment on warranty and reliability issues.

Supposedly there was a design change awhile back for the Monster box ??

I might end up with a 3.8 Atlas with HD input/outputs

Thanks again , Jeff
