They look like dumbells with rodends

Are they completely solid? Wouldn't they be a little stronger if they were drilled out a bit?

Here is another vote for the aluminum LG rods. They are amazing pieces of craftsmanship.

This seems to be a common misconception.Alot of metals and Fibers are stronger than MILD STEEL. This is what most companies refer to when they say their product is "STRONGER THAN STEEL!".Good AL (Aluminum) is "stronger" than mild steel. Ti (Titanium) even 6AL 4V(vanadium) is not as "strong" as good steel.Let alone twice as "strong". Some types of AL are superior to Ti under specific loads.
While I'm here Carbon Fiber is not "stronger" than all steels either. There are MANY kinds of steel currently in production and they offer some of the highest strength to weight ratios you will find.


If you want top strength subframe connectors get them made from quality American or British sourced ChroMoly (Chromium Molybdenum) Steel.

I guess it all depends on what materials you're comparing. Pure aluminum is soft like butter, iron is quite a bit harder + stronger but needs to be cooked into steel & mixed with a whole bunch of other metals to become a handy recipe like chromemoly steel. I doubt that those over-kill LCA's are made of a top grade Ti alloy, which makes them even more 'not worth it' IMO. When I said that Titanium would be great to make subframe connectors out of, I was being facetious because well-designed SFC out of a decent Ti alloy would be hugely expensive; a good steel alloy would do just fine in its place.

But for the record, Titanium IS roughly twice as strong as Steel, when comparing oranges to oranges:

Material yield point (strength) at 20 degrees:
Titanium gr.5 alloy: 830 min.MPa
Stainless Steel 13% Cr <410>: 350 min.MPa

When cost isn't an factor (like with fighter jets and nuclear subs) Titanium is used all over the place

You're going to compare it to stainless? Come on I thought you wanted a fair comparison?

Typical Strengths of common materials,103psi
Ultimate Tensile Yield : Sty / Ultimate Tensile Strength (pulling) =Stu
Ultimate Compressive Yield : Scy/ Ultimate Compressive Strength (crushing)=Scu
Ultimate Shear Yield : Ssy / Ultimate Shear Strength (slice through) =Ssu

Sty/Stu Scy/Scu Ssy/Ssu

1045 Steel : P.S.I x1,000 50-150/80-180 50-150/80/180 38-110/60-130
Titanium : P.S.I x1,000 75-140/85-180 15-25/25/40 n.a/55-110

Note: 1045 steel is a medium carbon steel.It is nowhere near the "strongest" steel manufactured. It is mid-pack as far as steel goes.

Ti is used for a multitude of reaons. Onoe of the major reasons is it's resistance to certain chemicals and corrosion. The USSR had so much of the stuff and so few buyers it skinned almost all of it's Subs built since the early 90's with it. It definitely is a wonderful metal with fantastic properties. In certain applicatios there is no better material to use.However, it is not "stronger" than every steel.

EDIT: Note the strength of Ti in compression. This figure is directly relevant to it's use as a lower control arm. Ti in my opinion would be a poor choice for something used mainly in compression.

Chad, thanks so much for the metallurgy lesson. Not sure of the relevance to the main topic at hand, but I've been enlightened nonetheless. Obviously you put in the research time for your reply. I now see the error of my ways.

BTW - I picked the stainless steel alloy pretty much at random from a chart, because of the Cr content (Chromium to those non-metallurgists out there). And to clarify, I don't think I proclaimed Titanium as a magic metal which is always better than ALL steel alloys. Steel is a wonderful material, and so is Titanium; let's leave it at that

Jeff; what is this GP you speak of? Is there a website with more information?

Ohhhhhhh, now I get it
GP = Group Purchase
For a moment there I thought you were talking about something totally different.

How does T6061 alumininum measure up in terms of compression strength as used in LCAs? Thanks

1045???? WTF???? is this what dumbells are made of????Why not compare Ti to concrete? (cheaper) OR Helium? (lighter). How about Helium/concrete alloy???? Helicrete????

I have not seen a 1.29 just yet, but I have seen plenty of low 1.3's on the back tires!!!

Not sure. That was an old photo LG posted before they were for sale. Mine came with red rod ends.

Jeff, I respectfully disagree, so how about this. Send me a set of your LCA's with rod ends. I will pull an LG LCA off my car, also with rod ends, and weigh both on a digital scale. I will take and post photos. If your LCA's are lighter, then I will buy them from you. If not, I get to keep them for free. And just to be open, I plan to sell the heavier set and use the lighter ones.

Do these lighter lca have relocation brackets to go with them? and which one is the lightest......???? Also, are they lighter than metco lca's????
