The main problem with the 12 bolt is how the torque arm bolts to the diff. It uses 4 bolts instead of the 2 through bolts and nuts that the stock and every other setup uses. Too many times have I read the bolts back out and people snap them clean off in the diff. Its just something you have to keep up on.

Thats only on Moser castings. Tim runs a Strange 12 bolt which uses the stock style bolt through design.

The 12 bolt rears that are available for these cars is a step in the right direction. The 12 bolts are well known for being a stout rear that was a factory option back in the day in many performance cars. You can have a 12 bolt in an early Chevelle, Nova, Camaro, etc, and beat the snot out of it and not hurt anything. Put a 12 bolt into a late model f body that uses a torque arm, make a couple 4000 to 5000 rpm launches at the dragstrip, and I can just about guarantee you'll have a lot more gear noise on the way home. The torque arm seems to distort the housing on the 12 bolts, and it seems to happen to all the brands of 12 bolt rears. This does not happen to the 9 inch rears, and there is no price difference between the 12 bolt and nine inch rears. As the horsepower in our engines keep escalating, most people these days go straight to the nine inch rear. The 9-inch has an internal rear-pinion support that also supports the gear end of the pinion to limit gear deflection under high torque loads. This seems to be the major reason why the 9 inch doesn't start whining after high rpm clutch dumps, when the 12 bolt will pick up noise. The 9-inch locates its pinion gear lower on the ring gear to improve tooth contact, better the 12 bolt does. The 9-inch also has a 0.125-inch larger ring-gear diameter and internal pinion support than the 12 bolt.
I'm not trying to start anything, just asked a simple question because I would much rather pick up a $1500 12 bolt than fork over 3k for a new s60 or 9 inch(since they seem harder to come by used).

Didn't know that, that is good though. Really the only problem I have ever heard of.

Thanks for that WF. That's a good writeup. I wonder if you can do any type of bracing on the 12 to help.

I have not seen any evidence of this deflection referenced in the above post in either the Strange or Moser units. The worst problem we have encountered is the bolts backing out of the Moser housings as was said before. We have had some extremely loud 12 bolts that were like that from day 1 from Moser though. Strange has always produced a superior product in my opinion which is why we became a dealer in the first place.

Little update for the start of the season ...

Went to the street car shootout on 4/6 with the new setup. (6 pt bar, K-member, ps delete, 2 step)

-First run was way too high on the 2 step, did the 60' pretty much sideways at 2.1 and ran 12.1 @ 121.
-Second run brought the 2 step down and the car spun but stayed straight with a 1.9 60' and went 11.8 @ 121
-first round of eliminations dialed in 11.50 and brought the 2 step down more. The car bogged a little and went 11.54 @ 120.8 with a 1.68 60'
-Stayed with the 11.50 dial in, brought the 2 step up a tiny bit. Tires were starting to come around and the car dead hooked a 1.56 60'. I knew it was going to a good run and was prepared to hit the brakes. Stabbing the brakes i went 11.30 @ 111.58 mph. ugggh

One of the first two runs ...
