Well now that I finally have the first 5 proto types ready to go!!! Not many have heard of me but you will all soon know me I hope. I will be at KOH with the Sixty9 on display and would love to meet everyone! Now for some specs. Drop Out Dana 60
Takes all Dana 60 parts "gears, bearings, setup kit, lockers"
High or Low pinion in the same housing
Symmetrical pattern can be used as a "high pinion, low pinion or flipped high or low"
8620 STEEL housing "not IRON or Aluminum" Very very strong. 2 to 3 times stronger then all other iron housings made.
Roughly 3/4" to 1" more clearance then any Dana 60 housings out now.
The bearing caps will be keyed so there will be no mix up and also making the side adjusters "miss fit" a thing of the past. This will also help eliminate bearing deflection on the carrier bearings.
These were designed, built, poured, machined 100% in the good ol' USA by Good ol' Americans!
Dan at Ruffstuff Specialties will be making all the housings for this new axle. I know I am missing some stuff and will post completed pictures and will start a general testing thread soon. See you all at KOH!!! Thank You Jason Ratcliff JRAT OFFROAD
So I am guessing these bolt up to a 9 in housing? Sweet I would like to talk to you about these at KOH will be there by sunday all the way from NJ. I am running 9in housing from RuffStuff hope these are in my price range:smokin:
totally different bolt pattern than a 9" housing...maybe they're making in-house housings as well? I think the name is simply because it's completely D60 materials with a 9"-style 3rd?
this was bound to happen eventually with the release of Portal Tek's drop-out 14FF axle. :smokin: I'm really digging the high-low pinion interchangability.
Holy crap 2 posts and I cant even get the 2nd set of photos up . The guys at Aberle Indurstrial MFG./ Arberle Offroad are the pattern and tooling guys and are the BEST is the business! The last pic is of the ALuminum center I had made so Dan at Ruffstuff could have something for a jig.
I had the same Q but this gave me hope that dana's will now be a quick setup without shim pulling.
Now, how about the pinion housing, you shim it to get depth instead of shims behind the inner bearing, or will it still be pinon stem shims?
Damn that's awesome... also want to know pricing... I'm guessing for many this would be a good way to get a high pinion front(or rear) end without spending $2k on the center section alone... especially if you already have a 60. I have a low pinion 60 front now so I could transfer my locker over which would be sweet if I wanted to change to high pinion.
I havent contacted any other vendors for housing but I have known Dan for some time and really like his housing. I also am not opposed to others making a housing and will work with anyone that would like to. There will be no shimming the carrier but there will be shims for the pinion. Thanks Jason Ratcliff
Make sure that who ever is making the housings has the capability and does machine the flange and bolt pattern after welding. I know ballistic and Spidertrax and Currie do.
How are you controlling pinion from walking under load?
I'm curious because the OEM gear sets don't have a pocket bearing like a 14bolt or a 9", and with the drop out pinion support, I worry that the pinion "carrier" will be subject to moving under load...
I was thinking about that also, but that pinion support bolt pattern is huge. Also I worry about the aluminum. Aluminum is 1/3 the modulus of steel and thus 1/3 the stiffness, so you really have to beef it up to minimize the deflection of that third member.
Yes these will be 8620 Steel center section NOT "Aluminum or Iron" The only thing that was made out of Aluminum was the jig I had built for Dan at Ruffstuff. About the size of the pinion support those are raw steel they will get machined taking a lot of the mass off them. Thanks Jason Ratcliff
Theres been some talk on the board here about adding load bolts primarily when using HP in the rear. Will yours have them, or was it given any consideration? Will the larger super 60 gears work with it?
The load bolts were a thought. Its not a big thing to add them if needed. I'm not sure if we'll need them though. As far as the Large 60 gears I'm not sure until I try them. You're talking about the 10" Ring Gear and larger spline pinion shaft ones right?
Very cool, especially the high or low in the same casting!
