torque arm issues

**stoney0803** · 06-15-2015, 04:02 AM

ok so recently i installed a 9" ford in my 2000 trans am, and when i did i also installed a spohn adjustable torque arm. took some minor modification to get clearance between where the torque arm mounts to the rear end and the floor pan but thought all was well, but when i went on the hot rod power tour i found that as i hit sharp bumps in the road the body would come down and hit the torque arm mount in the rear where it mounts to the rear end. on my way home it hit hard enough to tear a hole in the floor pan. m question is has anyone else had this problem and if so what are any possible fixes? thanks stoney 0803.

Did you contact Spohn about this issue ? There is nothing right about your problem with the torque arm.

Our tunnel mount torque arm, bolted to a Moser 12 bolt, also touched our floor pan slightly on full compression. I noticed this shortly after installation and simply ground the corner down a bit for some added clearance. Things are tight back there and not at all surprised that there are some minor clearance issues with beefier components. Are you still running your bump stops? Are they intact?

yes i did they told me to make sure i was using the bolt holes that were closest to the drivers side of the mount so i cut the bracket off so i could slide it over to the set of holes they were talking about and it still hits. think i have a plan to fix it by remanufacturing the mounting point on the rear end and cutting the floor pan and remaking that as well. was just wondering if anyone else was having any issues like this.

bump stops are intact. think i have a fix figured out by remaking the mounting point on the rear end and modifying the floor pan in the tunnel area around the backseats and making extensions for the bump stops.

Most people use the BFH mod and add clearance in the tunnel area by pounding on the floor pan to "create" clearance.

Now that you mention it Jon, I may have done just a little BFH'ing as well.

BFH here too.

BFH or maybe the gas ax.

Is there a good torque arm out there that doesn't encounter this issue? This was one of the next things on my list to do (after/sametime as SFC's).

Jeff used UMI and I have the BMR Trak Pak. I honestly think it's just inherent to the design. I don't think everyone encounters the issue, but many do.

UMI here as well. my only issue with it is not because of the brace. it's correct. My issue is with the custom 8.8 rear. It fits and all just its a little over too much to the drivers side.

Just how things are under there. Not a big deal imo - just keep an eye on clearances and adjust where you have to. Easy test would be to pop the shocks off, remove the springs and then run the rear end up and down through its full range of travel to see if anything hits. Be sure to check it with the bump stops in place and use lift points at the center, on the right and on the left so that you know for certain if anything is going to hit.
