I just don’t think it was machined right. It always leaked and re sealing it didn’t fix leaks. At KOH it locked up. Not sure if because low oil, because it likes to spit the rear output seal out of the housing. It doesn’t look to me like it broke whole teeth off of gears, they look like filings now. The center gear cluster thrusted into the case halves is why Josh is giving up on it.
For $3,900 dollars? Why? I’ve got several friends with MMW cases. The portal crawler guys seem to be having good luck with theirs. 3000 pound cars with tiny 4 cylinders and 10:1 axle ratios.
No no no no. The case I’m posting pics of is not for sale.
Mine was a replace-a-case and luckily mines only leaking out the rear output seal. I’ll keep a better eye on oil level. Looks like that’s what killed it to me. But case half is salvageable with some machining I would think.I just don’t think it was machined right. It always leaked and re sealing it didn’t fix leaks. At KOH it locked up.

My reason for thinking about one is that I already have a BUILT Dana 300. 4:1, 32 spline outputs and I want to change to driver drop. This case gives me the option to assemble as drivers drop or passenger which I find very useful.
You can assemble drivers drop. That was selling point for me as I passenger drop now going to driver later and I already had a fully polished 300 I was in to for $500 through some horse trading.
So you have the MMW or Behemoth? Are both MMW and Behemoth out of business or just MMW? When I goggled behemoth some "out of business" links came up but I thought they were still going and delivering products.
You can do that with the new Atlas cases built for the past 3 years at least
Behemoth Colossus case is $2445 and can be made driver or passenger drop....just as another option. If I was going D300....right now, that's who I'd go with.
I never thought MMW business should have been selling complete cases. Just sell replacement case and machined pins done. Similar to what TMI is doing with his new 205 cases. You just are hinging so much of your business on jb conversions which isn’t known to have stuff in stock.I get the desire to have an alternative to an Atlas because they’re expensive. What I don’t get, is having less transfer case for more money. An opted out Atlas II is $3300 with shifters. What are you getting in a D300 for $3,900 dollars that would make one even consider doing that? Y’all know that the gears and shafts inside of an atlas are bigger better than a D300 right?
This is from AA case builder right now. They’re delivering in 5 to 6 weeks right now. Randy Slawson often has them on the shelf and the last time he was trying to sell a couple he was asking $3K for them.
So a new Atlas @ $3k ish can be taken apart and switched between driver and passenger drop? Thats a standard feature now?

Yes
That case was a turn key build from MMW. That was NOT an empty case that Josh built, it showed up fully assembled. If the pin was too long it was MMW’s fault not the customers.
YEARS AGO!!!!!!!!!! I want to stress that..........YEARS AGO. I talked to the owner of JB conversions at the time John White (may still be the owner I'm not sure) and he said that his 4:1 dana 300 gears were bigger and stronger than the Atlas gears. As I remember him explaining to me the Atlas was originally loosely based off of a Dana 300. Gear 4:1 gears for a Dana 300 are based off of 205 gears.
Pics of them side by side are still on the web....
I just configured a fully opted race case, as I would put in a U4 car (which anyone can do at any time just FYI). 3,800 and change for “super finish” gears (rem polish) 300M outputs etc and these are the ambidextrous cases. Same case is driver or pass drop with no parts needed to change it
Yeah, at that price point ($3500 and change without tax)....hard to beat the Atlas.I just configured a fully opted race case, as I would put in a U4 car (which anyone can do at any time just FYI). 3,800 and change for “super finish” gears (rem polish) 300M outputs etc and these are the ambidextrous cases.

I’d also do a Phenom case before I’d consider a Colossus case. A 2 speed with 40 spline outputs as I’d stick in an U4 car is $3,800
$3,400.

Ah fuck man... you're just trying to over complicate things by making them easy
Wonder if early production before the figured out that discrepancy in pin length. Either way that is my initial guess, would be worth checking before rebuilding that case. I do like the MM case, have built two but reused original D300 guts in both.
The shifter design is far superior to the original Dana 300 that you have to completely disassemble the t-case to adjust the detent pressure. 5/32 Allen wrench and 11/16” wrench in 30 seconds it’s done on the MMW 300.
The shifter set up in the Behemoth looks pretty simple too...but I wonder how durable it is and how well it actually shifts when in use.
The Behemoth shifting setup is being updated, worked with it over the past couple days helping dial one in. Still not up for production, but close. Jesse Haines had his hands in the development.
