This oem trac loc peaked my interest since has what looks like solid steel or iron disks. Since is like this, I can belive him that this would have a good lock up. The oem disks are out of stock from what I find and replacements look to be sintered iron/bronze discs. So if have to rebuild this in the future, not sure if would be the same.

It was a bit dirty and tought to pull it apart for cleaning but found the packs had very good load on the siders, so left it as is and cleaned best could. Will run it a short while and change again so the oil can pick up whats left of debris.

The bearings had a lot of play, so where do for replacement. Just cut cage and then the race, then there off.

To install them, you have to get a bit creative. Get them started with wrenches till going on true, then can buzz them on the rest of the way. At this point I also have the 3:55 gear swaped over with new bolts, they where a hair longer but with in margin of error.

In deliberation there is mean to get the zf5 to have more feed back from the shifter, so will give it a shot if one is found. I would be looking for the one off a 460 with the wide ratio spread. I would be open to grabing the nv4500 hd off a dodge v10 or cummins if is found first. The spread is about the same for both and is a range I like.

A adaptor could be had to bolt the nv4500 to the bell I have and then need a nv271 with dodge input swaped over.
