i have a question about the spohn torque arm. if i have a stock rear end now and want to someday upgrade to a 12bolt can i somehow do this or do i have to buy an entirely new torque arm specifc for the 12bolt? very expensive for me so just wondering. thanks.

The arm should be compatable with all stock and aftermarket bolt in rear axles. Don't forget you need longer.bolts for the torque arm.

i was confused i guess because they ask for the option of which rearend u are running. so i thought maybe they build it diffenent for a specific rearend setup.

86 is right.

The difference in ours is in the bolt kit only. The 12-bolt requires one long bolt and two cap screws instead of the traditional two long bolts.

orly? the strange 12 bolt uses 2 long bolts and i though the moser used 4 short ones? is it really 2 short and 1 long?

I thought that's how it was. I'll have to go in the assembly area and check. I thought from memory it was one long and two short...

you could be right, i just always though/was told, the moser used 4 short bolts.

We have a 12-bolt, a 9" and an M9 in the back. I'll check it out. If I was really sharp we'd spec a proper bolt kit and put it on our site.

anywhere i can get the proper bolts? so what exactly do i need for stock rear end. or just what i have?

Our bolt kit with two through bolts utilizes longer bolts than factory. I made a note to check the length tomorrow as well as publish the 12-bolt solution. Got busy today...

ok thank you. keep me posted. also still very interested in the kmember installs. keep me informed on that as well.

I made it to the install area. For our T/A bracket on a factory rear, you'd need our hard-to-find longer bolt kit. This kit takes into account the thicker than stock bracket on our T/A.

And //86\\, it turns out the Moser is 4 short bolts.

The photo here shows the front lower bolt with a 1-1/4 L, 1/2-13 cap screw. I'd imagine a 1-1/2L would be a bit better. The two front holes are "through".

The two rear holes are blind. The depth is such that the hole plus our bracket plus a washer equals 1.815". I'd try a 1-3/4" for max thread engagement as long as you're sure the bolt doesn't bottom.

With all that said, it seems like Qty 4 of 1/2-13 x 1-1/2 L would be a good place to start on a Moser 12-bolt.
