Torque Arm Fab

started welding up some boxed steel pieces to an extra arm i had laying around. figured it would make the stocker more ridged. im too broke to get a cromoloy one, so this will have to do untill i get the money saved for the BMR piece. ill have another picture of it soon when its finished and painted. what do ya think? i still have 2 more boxed pieces to weld on the other side. the picture makes them look smaller then they really are

That qualifies as my kind of mod: Cheap or free

Let us know how or if it improves traction, that's a really good idea.

i looked at the arm again. im going ot leave it the way it is. its definetly going to be strong enough without adding the other 2 pieces. i plan on brushing it down with a knot brush on the angle grinder, and painting it. ill prob have a finished product by tuesday.

as for traction, i couldnt even tell you the gain i would aquire. i built my whole car up. started from a base berlinetta modle with the carbed 305. now i have a 362 and TONS of goodies under the hood and on the suspension and havent driven the car yet. so i wouldnt know the gain it gave because of all the other mods i have under the car. if you have an extra arm laying around you can send it to me and ill fab you one if you like. i have a lot of steel left to make plenty more. the boxed steel is solid BTW, not hollow. i thought i had an extra arm in the gurage, must have junked it when the guy came collecting steel for the junker. let me know

I have an extra torque arm lying around. I knew I wanted to try and box it up somehow. Thanks for the pics. I will post some pics when I get mine boxed up too.

I like the idea - I was wondering who has done any home made fabs to the torque arm

I got some sections of plates welded in the inner grove 5- 6 inches apart to add strength overall (I hope)

Each plate is about 4 inches wide and they narrow with the torque arm as it nears the front

I haven't installed it yet -

The only issue worrying me is how close does it get to driveshaft in motion

I know I have clearance at rest but I wonder how much it moves in full flight inwards??

I will try and post pictures later

*I think* It shouldn't move inwards under load unless it's distorting. It's only purpose in life is to prevent the differential housing from trying to turn the opposite direction of the wheels under tq load.

Thats why alot of the higher power thirdgens with stock tq arm and mount will shear the mount and thump the tq arm into the floorboards

I thought about doing that for awhile myself. Eventually I concluded that the torque arm had enough significant design flaws that boxing wouldn't fix that it wasn't worth it. IE was too heavy already, wasn't adjustable, was mounted in a bad place, and a weak mounting point.

A much better fabrication project would be to make your own arm from scratch. I changed to that plan, got my design all worked out, but got lazy and bought a jegster arm

no way. it stiffened it right up. the mounting location is fine, i wouldnt alter the mounting location. only arm i know that mounts in a different spot its the sphon arm and i heard they have some problems. theres a reason why the factory put the arm where it is. the arm realy isnt heavy... im sure the extra few pounds wont hurt, im not stright out racing it. pinion angle is really for strip i would think, i have a lot of buddies that race with the stock angle and do fine. they also use a stock arm. i think practical when doing things to my ride. no point in having a power house for a car(super loud exaust, huge cam etc..) thats intended for street use. eventually im going to get the BMR cromoly arm anyways, this is just to hold me off untill i get the money

actually i hate to hack on the guys work, but what he did there will do absolutly nothing for strengthening the TA. all that will do is add weight to the car.

If anyone is considering this as an alternative to buying a aftermarket TA, your just wasting your time IMO.

When I get some time, I plan on making a tubular torque arm out of rigid black wall tubing. From what my dad was saying, this stuff is quite a bit stronger than standard tubing due to the fact that it has a thick sidewall and is seamless. I'm gonna try and fab up a solid chassis mount for it as well.
