http://michiganmetalworks.com/store/...&product_id=78 Works with a dropmember says it will lay out 33.5 od tire.

Re: Anyone seen these control arms yet
 

Oh, ah.

Very nice. and pricey!

Re: Anyone seen these control arms yet
 

Actually cheaper than alot of tubular a-arms.

Re: Anyone seen these control arms yet
 

I have seen his s10 ones in person they are heavy and his special upper ball joint he calls a jeebus joint does out flex any ball joint i have seen.Ridetechs a arms are a grand kp links are over a grand so its not that pricey next to what is out there.

Re: Anyone seen these control arms yet
 

What material is used?

Re: Anyone seen these control arms yet
 

Those are from Jeebus. He is a member on here. Looks cool.

Re: Anyone seen these control arms yet
 

So, if they work with a DM, does that mean they won't with a stock x-mbr?

Re: Anyone seen these control arms yet
 

The upper would but the lower uses a different cross shaft. The stock cross shaft bolts to stock crossmember with u-bolts. The PB member uses something different.

Here's a complete listing of the Chevy a-arms available.

Re: Anyone seen these control arms yet
 

Any idea on materials?

I'm guessing these are for the frame dragger and not the corner carver?

Re: Anyone seen these control arms yet
 

Makes sense why the pic doesn't have one on the lower ;)

Re: Anyone seen these control arms yet
 

They look neat but I would worry about those things folding up. Is there some form of triangulation I'm not seeing?

Re: Anyone seen these control arms yet
 

The black ones look bedazzled. http://forums.ratedesi.com/images/sm...ic_thrust2.gif

Re: Anyone seen these control arms yet
 

I could be wrong, and I'm sure I am, but they look like they use a 1/2" to 3/4" plate. If you can fold those up, you're beating the crap out of them. :lol:

Re: Anyone seen these control arms yet
 

These are steel plate your frame would bend before this will.

Re: Anyone seen these control arms yet
 

HAH! I was wondering if that was a chunk of plate steel. Unsprung weight.. whats that? ;)

Re: Anyone seen these control arms yet
 

you would be surprised how easy it is to bend flat 1/2" steel plate ...

Re: Anyone seen these control arms yet
 

About 32 tons/foot on a press break...

Sounds like a lot to me

Re: Anyone seen these control arms yet
 

those are pretty bold numbers considering you don't know the tensile strength or the type of steel used.

p.s it's a press brake, not break

Re: Anyone seen these control arms yet
 

Please excuse my spelling error.

That was just a general value based on mild steel with a 60,000 psi tensile strength. The uppers he produces are 1/2" steel plate which is more than adequate as the upper arms are locating devices for the spindle and most all of the forces are tension and compression type forces. I believe his lowers are made out of 3/4" plate, and while I do not know the exact material he is using I would still commit to saying that they are adequate for the job. It will take a considerable amount of force to bend a 3/4" plate that is roughly 10" wide and 18" long.

Re: Anyone seen these control arms yet
 

even at 60,000 psi tensile strength, 1/2" plate can be bent with as little as 10 tons under the right conditions (angle & width of bend, etc).

10 tons is really NOT a lot of force when it comes to the dynamics encountered in a suspension system with 3,500 lbs. plus riding on it. I'm not saying they aren't quality components, but if their design is truly "better" then I think the OEM's (not to mention the applications in motorsports) would have been making a-arms out of flat plate long before now due to the big decrease in costs to manufacture and shortened lead-times.

No flame meant, just stating the obvious from my perspective: 1/2" flat plate with NO supporting gussets? No thanks, my safety along with my passengers and everyone else on the road is not worth the chance.

Re: Anyone seen these control arms yet
 

I will disagree, but now the OP has an opinion from both sides with which to make his decision.

Flat plate arms are not a new idea and I believe have been used in the off road market for some time now.

Re: Anyone seen these control arms yet
 

Offroad as in rock crawling or Baja 1000?

Even if the steel was stiff enough to resist bending at the airbag mount, I highly doubt those two little bushing arms can resist any bending. I would be concerned about cracks forming at the welds and on those arms. Steel is a strong material, and you can design an arm to be lightweight and have infinite strength for a given application, but these arms look to have a finite lifespan on a heavy truck. I wouldn't want to do a chuckhole test with those arms.

Re: Anyone seen these control arms yet
 

With regards to the offroad aspect I don't know first hand. I have seen it discussed previously. I debated about even mentioning it and probably shouldn't have.

At any rate, I stand by my opinion that these arms would be more than adequate on a day to day basis. There is always a scenario where something will fail and that can't always be predicted.

I plan to run these same arms on my truck and have no concerns in doing so.

I like the flat plate my 2 cents I was going to get mine from this place http://www.dallashotrodparts.com/
