I know El Polacko is doing a lot of rear suspensions with torque arms and I really like the way they seem to work...and after doing a search and looking at some pics on here, I have a few questions. First off, does the torque arm have to have a pivot in line with the front U-joint on the driveshaft? It seems like this would be necessary, but does using the little extra link on the front of the torque arm get rid of the need to align the two pivot points? Secondly, from what I can tell, the torque arm need to be rigidly fixed at the differential, correct? And the lower 2 links need to pivot at both ends right? I believe the lower links should be parallel to the ground at ride height, but is there any restriction on whether you run them straight forward, or angled in toward the center of the chassis? How about lower link length versus torque arm length? Third, is there any adverse affect to using airbags with a torque arm rear suspension? Any suggestions on airbag placement in regards to both ride quality and lift? I'm doing a '49 Chevy Fleetline, and it's got a Mustang 2 front and I Z-ed the frame in the front also....I want it to lay on the ground, but I also want it to ride nicely. I was going to just go with a triangulated 4 bar, but now I am considering the torque arm setup as well....any help or advice is appreciated.
