=180lbs

Add the knuckles
=245lbs

Complete axle at 625lbs means housing with gears and carrier should be about 380lbs

Jeep LJ sub 40" tire. I want to wheel it and road it with full confidence in nothing failing.
The HP 60 would work but heavy. I don't trust a HP44. Not interested in any of the JK / JL versions of a D44. They are strong but not a good foundation for growth in my opinion.

Planning a fabricated Ford 9" housing, 05 up outers 1550 shafts.

I think I would be ok at that point without getting too heavy and keeping ground clearance.
If I did want to go with a bigger tire or stickies I could without fear of failures and have a solid foundation for any future upgrades.

I ran flipped low pinion 9"s in my rear engine buggy and was impressed with what they will take being driven on the coast side of the gear. A low pinion front with a load bolt would probably work just fine.

Just thinking of other ideas… this might be dumb but what about a Jana 54 center with 05+ outers? Keep the ground clearance up on the diff, keep the driveshaft up with HP, potentially keep the weight down compared to traditional one tons, and improve the strength for future with the 9” ring gear in high pinion? Super duty steering characteristics, possibility of 1550 shafts but that’s probably unwarranted with the center strength?
 
I guess the thought was 35 spline is easy for jk 44 center section and 35 spline is factory for 05+, so you’re keeping off the shelf part’s instead of the machining needed for the 99-04 50/60. So even if it’s 05+ just to run 1480s at least it’s off the shelf stuff.

Having done none of this myself, retubing a jk44 sounds easier than shaving a 50/60 and machining the hubs.

But, I didn’t factor the Jana into the carrier… does the J54 setup use the D44 carrier still?

99-04 D50 will accept 99-04 35 spine inners. Just need 35sp side gears

I'd imagine whatever method used to put D50 gears on a D44 carrier could be reversed to put a D44 carrier in a D50.

It's easy to get into "not worth it" territory either way.:laughing:

I’m talking about outers, you’re still machining outer hubs to run 35sp then in the 99-04 category

True, but “not worth it” is relative. Doesn’t sound like many other high pinion non-tons option is reasonably available with a 9” ring gear based off the discussion in this thread.

Dynatrack seems to think the idea has merit considering they offer a Prorock 44/60 hybrid

ETA: maybe step it up with a Currie 44 center chunk? I don’t know if they’re available by themselves, I thought I’ve seen in the past they’ll sell just the center chunk.

What does this nonsense have to do with high pinion 9” / 10” gears? Isn’t there already threads for superduty bs?

Back on page 1 where it turned from no reasonable availability for 9” / 10 HP setups and the suggestion was “seriously consider something else”

You must be new to forums. Name one thread in the history of forums that has strictly only ever talked about the original topic… take a chill pill. You got something to add about 9” / 10” gears or you just gonna clutter it up too?

Boring the outter bearings is leaps and bounds easier than building a custom housing.

If you want a D44 center, I'd think JK outters are a better match personally.

What are those doing for these days? Around 1300 a set?
Click to expand...
Had to pay the bill today, $1400 a set. US gear is back in biz but they’ve got some catching up to do. We contacted TrueHi9 to see what they had to say about potential availability. Their official response was that they aren’t cued up for US gear yet. Gearworks is the bigger company and have dibs on all the blanks in the 9310 for a while.
 
Right on, I was talking with gearworks about 6 months ago with pricing out bare 3rd, pinion support,r&p, and a couple misc things. Almost 3k... my curie hp8.8 is still larger than the my hp8 toy I used to run. I'll keep saving change and hope what I got stays together till I can afford the upgrade.

I was working on this dumb idea. 77 F150 HP44 with 99-04 D50 outers. The plan was Jana 54, load bolt, girdle cover. 35 spline inners/outers.

I put the knuckle/tube sections on the HP44 housing this week and I believe I've changed my mind. I think the weak link moves to the pinion splines.

I'm looking at a fusion D60 for around the same money.

You should cut out the Dana 44 nonsense and put in a high pinion 9” / 10”.

Or just order the fusion D60 and go wheeling…I like building stuff, but I want to eat this cake, not bake it

What's the point of doing that instead of just modifying the D50 for your application?

Packaging, the 44 center section is smaller. Mr Jantz makes all the gee whiz parts to make the 44 housing fit the 50 gears, PLUS the load bolt AND the Girdle. I'm not sure if the 35 spline 44 ARB would work in the 50 but I suspect it would so that's probably a wash. The 44 center section had better ground clearance, so I like that. I also think it was considerably lighter, although the weight difference was probably not as much as I'd hoped. I also have a truss for the 44 housing that puts all the brackets where I need them.

I also occasionally have a thing for weird one off builds.

Alas, I've gotten over all of that and I'm looking hard at a full blown 60.

I played around on the website configuration and at first I was thinking yeah I guess that’s not that unreasonable, I was actually surprised it was about the same price as what I was penciling out for my “budget” SD60 build. Im figuring $3-4k depending on if I go spool or arb and whether I use stock lock outs or add the rcv hubs, but I got my housing for $100 and have brakes already.

Then I realized that the fusion stuff doesn’t come with anything from the C out, so add another ~$1,500 to the price on the site

That’s a spendy option, but if you can swing it more power to you :flipoff2:
 
There is a new 5.29 Amboid cut gear on ebay for 510. For a HP rear setup. Guy had a HP10in 5.43 with a 40 spline ARB setup as well. Was able to get it for $3650. Apparently these were recovered from lost shipping pallets.

No way.


What is the item no. on that. We may have bought the same one… So I’m curious to see how that goes.

Said there was 1 in stock let me check out and everything. So hopefully there was more than one and we both don’t get scammed.

Was the seller named “Midnight Metal Works”

Sorry, too soon? :flipoff2:

These are not Amboid gears nor a reverse cut gear. These were made for us by US Gear for desert racing and are a ground tooth gear we had problems with. I would not purchase these.
