help me build some bad mofo links

4130 2 x .500
1-1/4" Evolution Joints

You bend or break that chit you would make a lot of people proud.:bow:

so why would shannons crew think the 2 inch aluminum is enough beef? no one thinks they will hold?

A CK5 survey never kept a suspension link from bending in the past.... :rolleyes:




What does the Campbell rig weigh? What does YOUR rig weigh? The FS Values in ExcelCAD are calculated based on the vehicle weight. The heavier the rig, the lower the "margin" will be for a given tubing size. In other words, it's dopey to copy a Shannon Campbell suspension on a vehicle that weighs 2X more...

If you want to be smart, put his values into ExcelCAD and see what the FS values are for his design.....then make sure that your design has numbers that are at least as good. :deal:

I have 1 1/2" aluminum tie rod. I put the whole weight of the front end, tires and axles hanging in the air of the center of the tie rod. The tie rod deflected about 8" and returned almost straight after I got it off the rock but there is still a little bit of bow to it. I tried to straighten it but had no luck.

I think 2" would hold up for a while as links if you didn't have to much weight on them but I think they will eventually start to bend under constant abuse.

Im a bonehead who has no engineering degree or anything... but if I am going to run a bent link (cool idea for ground clearance!) I want the thing trussed over its entire length to discourage any type of bending. I'd add some material, like this... (sorry for the crappy paint job, lol):

Just looking at the installed pics, I don't think the added material on top would hit anything... and it would gimme some peace of mind that my links ain't gonna bend (significantly anyway) no matter what I do to them.

That style of truss wouldn't do much for the types of stresses that link is seeing.

Bingo. When you accelerate the link wants to squish and when you brake it wants to streach

I designed them BTW.

The gusset goes as far down as it does out. This brings the loads near closer to those as a strait link . It is on a #6000 longbed truggy that has seen DD for a year with no problems. There is a small angle ridge on the top of the link. That is more to tell if it has bent (the welds will deform and the paint will chip).

The WMS guys run simlar set ups with even more drastic bends.
 
I was actually thinking about the stress of a dropping the entire rig 10' onto a pointy rock about half way down the link...

Well..... so far my "uni-link" under the Marvzda is "unbendable".... I've landed on it alot and all the lower link force goes thru it so it sees a good amount of Force.

It is 2" [ ] x.188 wall sleeved w/ 2.5" [ ] x .250 wall.

im pretty sure they are running 1.5 inch on their comp rigs, I also made him aware what the links would be used for, but im all for someone who could make them in the same time frame, tell me they will work and I could just bolt them on..

so far shannons crew is the only ones local who replied they could.
 
I can tell you from practical experience that 2" .250 DOM will work and hold up.

If the strength numbers come back for the Al to be near the same I would give them a shot. Its a buggy that weighs in at roughly 4500 lbs not a true fullsize.

Try the Al and see if it works.
 
jeep on rocks and 52's

This is my buddies jeep that twoslo was talking about earlier. Nice 4link setup. I'm not a jeep fan but this is bad a$$!!!!!! I have some pictures of me standing inside the frame when the body was off. I'm 6"4" and the framerails come up to my freakin' chest!
