Hello,

Since you are running a larger rear end the torque arm will sit closer to the tunnel like you are experiencing. The Moser 12-Bolt has a larger housing, the larger the housing gets the further it will push the torque arm to the drivers side and closer to the tunnel area.

Is the vehicle lowered? If so this makes the issue more noticeable.

Do you have an adjustable panhard bar on the car? An adjustable panhard bar allows you to center the rear end under the vehicle. Most likely the rear end is not centered and you should have some room to move it towards the passenger side... this would gain you clearance for the torque arm. If you don't have an adjustable panhard bar and the car is lowered it will sit extremely close to the tunnel since lowering the car can offset the rear end.

not lowered, stock panhard bar. the thing is, i don't think your old style bar was so close to the tunnel. when i measured the rear end it looks allmost centered give or take 1/8" .

let me know what you think, for now i just beat the tunnel in flat where it would have hit. seems to get on and off the trailer allright. will fix this week.

thanks joe.

Hello Joe,

Yes making clearance in this area is the best solution. My personal car is stock height with a Strange S60 rear end.. I let the torque arm clearance the tunnel for me after a few good launches

The newer style torque arms use the same mounting bracket that mounts to the rear end as the old style.. just the arm itself was changed.

Hope that helps,
Ryan
