Oh, ah.

Very nice. and pricey!

Actually cheaper than alot of tubular a-arms.

andrewmp6 · 10-05-2011, 08:11 AM

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.

OJ1988 · 10-05-2011, 10:06 AM

What material is used?

aggie91 · 10-05-2011, 11:03 AM

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

tubbedII · 10-05-2011, 12:52 PM

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

aggie91 · 10-05-2011, 01:54 PM

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.

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

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

OJ1988 · 10-05-2011, 02:23 PM

Any idea on materials?

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

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

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.

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

funkytechmonkey · 10-05-2011, 10:58 PM

The black ones look bedazzled.

andrewmp6 · 10-06-2011, 12:51 AM

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

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

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

Sounds like a lot to me

*Shane* · 10-06-2011, 04:31 PM

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

dv8customs · 10-06-2011, 05:21 PM

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.

*Shane* · 10-06-2011, 05:46 PM

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.

dv8customs · 10-06-2011, 06:33 PM

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.

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.

dv8customs · 10-06-2011, 09:27 PM

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/
