"We solved this problem with a steel friction ring that attaches to the diff cover, covering the bolt heads and providing a flat friction surface."

That does not sound like it would work well at all.

By the time you upgrade everything in an 091 to make it semi reliable you could have spent a little more and bought an HV-1 and had a much better trans.

There's no reason the concept would not be good. Mendi does it as does the HD/industrial diff market. The implementation may/may not be well executed. I can't find a pic anywhere showing the friction ring. I saw one of the case mod,looks good and can't find it now, but not of the friction ring. My biggest concern would be the weakening of the case from welding in the load bolt boss between the ribs.

it's not a bad idea but if the power is overpowering the trans then a stronger design would be better. I am sure it would work though. the hv-1 or pbs trans would be a nice choice but more expensive. if a guy had the means to do this mod himself then it would cost effective.

The albins,fortins,mendis all use a load bolt as do OEM HD stuff in some apps. Sometimes you just can't avoid ring gear/carrier deflection under extremely high loads and the load bolt is the only band aid there is.

All the Ablins/Fortin/Mendi tranny's use 10" or larger ring gears that have enough room on the backside of the gear for a load bolt. The whole mounted on top of the ring gear bolts deal really makes Me wonder how rigid it actually is and how parallel with the ring gear it is. A few thou out and it would do bad things. If it moves around at all due to a non-rigid mount, it's worthless. I also think having it that far from the ring gear will create problems.

I agree completely but at this point I can find no info on how it's done/how mounted/radially or somehow in line/heck I don't know. I wish there was SOME kind of specifics to be found. To be honest I have my doubts like everyone else especially after the TW mini-diff debacle. I still say the concept is sound but the devilish details may be an issue I readily admit. I still wonder if any purported benefit is a moot point if the case is weakened in the area of the added boss due to welding. If heat treated after welding it would be all warped. Probably warped to hell due to the welding anyway.At least internal stresses would be induced wouldn't they?

I would have to say yes, similar to having to line bore a T1 case after it has been welded behind #3.

At least when you do a 9" your using an existing hole even though it's not braced all that well on the factory cases. I've always had dreams of doing a roller tip load bolt similar to a roller lifter. You could afford to have it set a lot closer to the ring gear then.

True but I'm not sure a roller of a smaller size as would be necessary, would be up to the task.

How bout a big ass ball bearing sitting in a spherical seat?

By ball bearing, I meant singular.  As in one ball.  I don't think it would be pricey. machining the seat might be a challenge, but you've got all that special equipment for both machining and heat treat.

I don't think a single ball could/would work. Sketch something up. Maybe I'm missing something.
