WANTED: 4 Link Crossmember pics

I need to see some examples of how people have made a crossmember for their lower arms on a Double Triangulated 4 link.

Whether you tied it into the Tranny crossmember or not, it doesnt matter.

I used 2x2x3/16" box tubing... I had it drop about 2 inches bellow the frame rails so I could get a decent roll center and more squat

Mine is 2x2 box welded to 2x2 angle iron which bolts to the factory skid holes. I also have plate welded on the inside of the frame rail that bolts to the 2x2 lateraly.

This is when I built it, I have since made the skin removeable. I still need to drop the whole thing to get the t-case or trans out, but I needed the lowers as long as possible.

Dude, if you're about to spend the cash it takes to build a 4-link, you should seriously consider buying a star. There's a wealth of information behind that search button.

Having spent hundreds of hours searching this board and others, buying every suspension book out there, spending hundreds of hours designing my first double triangulated rear four link using a CJ7 aftermarket chassis now starting my front double triangulated link suspension, not having yet a running chassis to fine tune, nor do I consider myself being remotely close to being considered knowledgeable my observations are:

1. You have to define what vehicle it is going in.
2. You have to define what tire size your using.
3. You have to define the wheelbase, and if any stretch will be used.
4. You have to find a rough weight of the vehicle.
5. You have to state the axle width, and size.
6. You have to define the desired ride height.
7. You have to decide what modifications to the frame will be necessary.
8. You have to state what Transfercase is being used.
There are a few more parameters that need to be defined.
If this is not part of your question then your just window shopping for pretty pictures without any knowledge of what your seeking. The need to "see" what others are building are only applicable to them and their rigs only. Using the parameters that they had to design around.
I myself don't have a problem helping anyone but for me just to post pics for you to see without a few needed inputs from you, my pics are worthless to you.

Pics are never worthless. If you find something you like you can always adapt it to fit your application. Pretty much all I look at is desert racing fabrication. Most of what they do would never fit a rockcrawler or even a 4wheel drive, but the principles are priceless.

Mine was a cross member but the new doubler was so long I need to keep the bottom open.

All this affects the crossmember design.
He's mine for what it's worth
