I am in the process of putting a new everything in my car, engine, trasmission, suspension.. The tranny is a th400 and i saw that spohn sold a th400 torque arm/crossmember for my car (88 iroc) so i ordered the Chromoly one.. On the downside i didn't do much research and didn't realsize BMR sold the Trac-Pack which i like alot, however its too late now.. Anyways my Q is how is the Spohn th400 style torque arm that i ordered?? Good Bad Ugly?? Any info is good info, thanks ahead of tiem for the replies..

The Spohn still relocated the lifting point to the crossmember rather than the transmission.. Any comments??

Thanks in advnace! Mike

 

Nothing wrong with the Spohn torque arm however you didn't really need the chromoly version.

Having the torque arm attach to the crossmember takes the load and stress on the tailshaft housing off the tranny and moves it to the chassis.

 

ive heard the arm makes clunking noises when the brakes are applied. im not sure if its totally true though. my whole car is BMR and i have nothing but good things to say about them. but the spohn products are nice too

 

Ya i may have gone a little overkill with my chromoly parts, but i'm desparate to make this thing as light as possible, so i went for it.. And i know it is good that the torque arm relocates to the crossmember but i feel the BMR Trac-Pac is better, i wish i woulda seen it before hand, oh well too late now.. Waht did u do for a Torque arm ??

 

I ran a Spohn torque arm for a couple of years. When I finally installed a tranny with a transbrake I also switched to a 9" diff. Instead of trying to fabricate a bracket to the 9" diff for the torque arm to attach to, I installed ladder bars instead.

 

i'm buying a bolt in moser 9" pretty soon, i figured it'd have a bracket on it since its bolt in.. am i wrong? *fingers crossed*

 

A "bolt-in" housing has all the mounts to attach the factory suspension components. That's why it's called a bolt-in.

That's also why you can't just go and find a junkyard 9" or 12 bolt and install it. All the other brackets can easily be moved over however there's no easy way to attach the torque arm.
