While driving to the Y, a z28 drove up next to me revving and lunging, so I couldn't resist but to downshift. When I downshifted I didn't even get a chance to hit the gas, and just heard a BANG, and a horendous metal on metal sound. I limped home, and knew what it was since this is the third one. I looked under the car, and the bolts for the torque arm to rear end ripped through the holes on the torque arm. So before they were ripping out of the rear. Now they ripped through the torque arm.

I feel like I have just been putting a bandaid over the same problem. So I searched around, and found that byunspeed has a Sphoon, tunnel mount, adjustable, torque arm with a drive shaft loop for sale for only $350. So I will be ordering that today or tomorrow, and hopefully never have to mess with it again.

 

Good job

 

yeah, with a 12 bolt, I went through 2 stock tq arms before I got my spohn. I tell ya though, I really dont like my spohn tq arm. Makes way to much noise, and moves around way too much. I would look into something like a BMR, or even UMI. Just my $.02

Oh no joke? I was thinking Sphoon was about the best. What would make the BMR or UMI not as loud and not move around as much?

 

Your using a moser 12bolt arent you.

 

That was going to be my question too - Moser 12-bolt?

 

get rid of the moser 12 bolt

 

Lol yes you are all correct.

 

Sorry to hear you've had problems with that again, that sucks. I remember reading one of your other threads about this.

Did you happen to see this thread: https://ls1tech.com/forums/suspensio...destroyed.html

there is a lot of talk about the moser 12 bolt and torque arms in general in that thread, not just the UMI and some good thoughts and ideas in there.

I don't think you're going to fix the issue just by going to one torque arm over another, damn near every kind of torque arm out there has been destroyed or damaged in some way with Moser 12 bolt rears.

 

Oh cool, I haven't seen that yet. I will start reading and see what I can learn. Thanks!

 

Buddy of mine had a Spohn on his stock height Z28 and it rubbed on everything!

 

If you have any questions regarding our set-up I will be glad to help!

On our tunnel mounted torque arms we use a polyurethane bushing mount on the torque arm and the torque arm mount itself. This makes for a much quieter operation over the others.

Byunspeed also carries UMI products

Thank you!

how does the 12 bolt tear it up?

 

Any and Every way you can think of, from my experience.

 

So based on observation since your going to be on your 4th torque arm thus far and seeing how they are about 400ish bucks a piece (using a full length adjustable one for reference) your up to approxmiatly 1600 bucks just in torque arms, which is more than halfway there for a new/used different rear end that wont break things . Not telling you what you should or should not do just pointing that out, and im sure you already know it..

 

i have a spohn and love it. it sounds like the 12 bolt to me.

 

it has to do with the way to tq arm bolts on if i remember correctly. moser uses 4 bolts, two for each side of the mount. strange uses two bolts that go all the way thru the mounting tab on the rear. the difference is double shear vs. single shear...the strange way is just plain stronger.

 

The first one was the stocker, came with the car. Second was an aftermarket, 75$ out of a salvage yard. Third was another stock out of a salvage yard, $20. So i'm still under 100. You do have a point though. If I knew I could sell mine for a decent amount, and buy a strange or something, I would in a heartbeat.

 

Hat trick?

 

That sucks man, I would've bought a TA before a 12 bolt but that's just me.

As to what to get, I have all UMI pieces on my car. They have a great product as well as outstanding customer service, when I finish off my suspension with a K-member and a-arms they will be getting my business no doubt.
