Fabbed adj. torque arm

**ab923** · 11-01-2012, 06:09 AM

Has anyone made or heard of someone making their own adj. torque arm and if so, did you mount it to the crossmember or tunnel or what? I really think I can make one but I'm not sure where to start and haven't seen one in person to use as a guideline.

Just look at some of the designs available by UMI, Spohn, etc. I had a LGM on mine and it worked great for handling cos it was trans mount instead of body mount. Long pivot, better for handling/breaking, short pivot better for launching. Decoupled systems are best of both.

I made a custom adjustable torque arm on my Monza a few years back. Shortened it and made a mounting system inside the tunnel (removed it from the trans) so I could install a muncie (no torque arm mount).

If you are familiar with the Monzas (1975-1980) they are the predecessor to the 3rd and 4th gen F-body in rear chassis design, that's where it came from, just a much smaller platform.

This is a saddle mount style as another mounting option. I'm not running it as I want to go decoupled with one, but it came with my 9".

That's exactly what designed and made for the Monza.

any of you guys have an example of a decoupled one? whats your opinions on whats best as far as adjustability goes? like a heim joint you can screw in or out for pinion angle or maybe some assortment of shackles with predetermined pinion angles based on the tire im running or somethin like that.

The Global West Trac Link is a similar setup too. I run one on my car, and love it. Just a note, it doesn't work with the 9" without some fabrication. Not a major project though.

I think I've come up with a pretty decent design. When make my subframe connectors I will incorporate a cross member that bolts in and serves as a ta mount and driveshaft loop and helps with rigidity. Anyone heard if something like this before? Thoughts on how it may work?

**Mean Green Z28** · 11-05-2012, 08:28 AM

Yeah I've seen a setup like that and it also included a drive shaft loop. It was on a race car, so it was incorporated into the roll cage and wasnt removable, but there was enough space to get the trans out.

BMR's Trak Pak torque arm and I have it on my car.

What's your guys' opinions on adjustability? Are heim joints pretty easily accessible and affordable? I've never had to look into buying them

**bad idea** · 01-07-2013, 05:13 PM

On umiperformance.com (UMI) they sell replacement heim joints and adjusters. I plan on building my own torque arm to work with an 8.8. I plan on buying the heim joints, adjuster, and front bushing from them. It is the cheapest/quality option I found. They make a quality product, so they are bound to be good parts to use for building your own.

I strongly suggest you make it adjustable by the way.
