How would one go about getting the correct geometry when using a 9"? Would a Strange 9" be able to use an aftermarket torque arm?

 

Slimdawson and RedWS6...You have to check with the manufacturer of the TA. Spohn, and some others have two sets of rear holes in their arms..one for 10-12 bolt rears, and one set for the 9" because the 9" center ( and therefore the mount) is not centered under the car. The second set of rear mounts compensates for this and corrects the geometry front to rear to keep the suspension out of bind. I use and recommend Spohn stuff. Great quality, nice guys (Steve and Gordon), and very fair prices. www.spohn.net

lillbuch5555 would you wanna sell it or are you going to fix it and use it?

 

Im just gonna stick with the stocker for now, unless someone can show some REAL proof that an aftermarket TQarm will really help with 60fts, et's and so on. Every review in the rags always has some shocks or some other crap that seems to be the reason for the gain, ive never seen a TQarm only performance review.

 

have any of you guys ever used the hurst th 350 conversion kit?

 

Thanks aba383. I am assuming then, that one cannot use a stock torque arm on a 9".

Do these second set of holes move the torque arm laterally?

If you decide to sell the Edelbrock one keep me in mind. I'd like to modify it and use it.

Trust me... you ahve everything to gain by upgrading your tQ arm.... if you ever saw a quality TQ arm like SPohn or BMR... and the junk you took off your car... you'd ask yourself "why didn't you do it sooner"

There is a "BIG!" performance difference... to hell what anyone else says about a stocker compaiered to after market... no way I'd believe that bull... and usually it's guys who are running some maxed out Stroked blown nitrous rig that has bad traction from the get go and expect a TQ arm to help them get all 1200hp to the ground....

but seriously....after I installed my spohn the car bits noticably well... I eman like snap your 10bolt well...

 

Actually I have seen a Spohn TA(SWEET) I took 3 pages of notes and measurements and now have plans/drawings to reproduce one.

 

After reading this post I thought I was the only one with a busted torque arm. I also have the adj edelbrock TA, looks perfect before you install it....then snap!!!!! I made it to the first stop sign and dragged my [EDIT] back to the garage. I had to reweld the 2 pieces together and was out another $50. Spoke with a rep at Edelbrock, sent me 2 t-shirts!?

WWWWWOOOOOOOOOOOOOOOOOOOOOOOWWWWWyyyyyy!!

"This is a unique failure and isn't Edelbrock's fault" WTF kind of comment is that? What's your mailing address because I've got 2 t-shirts size L ready to go. BTW, my last Edelbrock purchase.

 

money has nothing to do with the type of product. the bars and their size are fine, the welds from the factory were bad. supposedly they redesigned and reprogrammed the computers that do the welds and now all is well. i had two and both broke, rewelded one and sent one back at my expense to edlebrock. i won't buy anything of theirs again mainly for customer service, not the fact their part broke however bad of a design it was at the time. once rewelded it's a great, lightweight piece for it's price. much better in comparison to overpriced spohn products but it depends on your application.

i would have to agree that if you have a car that is running 15+ lbs of boost and more built up you should be running something really stout and the edlebrock torque arm isn't it.

 

Regardless of what brand you go with get a TA that gets the mount OFF of the transmission. Years of stress on the tailshaft will take its toll eventually as metal does fatigue over time. Its no fun to see your tailshaft split at 6100 rpm...It causes lots of other bad (expensive) things to happen...been there...done that...I now have a Spohn cross member mounted TA with TWO loops...worth every penny.

Naaaaaaa

First ya tell the vendor what ya have....
Ya get the bracket that comes with the 9"-- ya get the bracket that comes with the TA--Ya install it all-- ya set the pinion angle and you're ready to go--everything should be as factory.
Seen several factory TA's break,that is why we got a Spohn and the race one and put a 4130 heim end in the front. The solid ends in the rear seem stout enough,if not they will get 4130 rod ends also.BTW the arm is streight as an arrow.

With the 9" ya can use only, (won't fit the other on a Moser) one set of holes--if you got a 12 bolt ya use the other set.

 

Racerdude, what are you talking about? That's what I said in the above post. The 9" center and TA mount isn't centered under the car. Which is why the Spohn has two sets of mounting holes. If you use a TA designed for a 10-12 bolt with a 9" rear the TA will NOT be centered front to back. Which is why I said to use the Spohn or any other brand that is designed for the application. You can set the pinion angle all day long, but if the TA isn't centered you'll add wheel hop and stress on the part. Maybe I wasn't clear by saying "stock rear location" I should've said "stock mounting holes"..., but it sounded like he was using an Edelbrock TA designed for a stock or 12 bolt rear on his 9" which will cause problems with geometry. If Edelbrock makes a TA for a 9" and that's what he used, then it broke soley because its defective.

Like I said in the above post ya got to let the vendor know what ya are running.I am sure the manufactures make them for both. Then no problem.The Sphon as you said comes with the adapter bracket drilled for both.
You can put a stock TA on the Moser 9" with their bracket, with no adapter. Don't see the logic in having a 9" with a stock TA, but to each his one.
I have also toyed with the idea of using the other holes(with modification) to move the TA more to the center of the car and ya would have to respace it in the front which is no big deal.
