Anyone have any good resources that deal with 4 links and how they work? I'm trying to do some research. Thanks.

 

i don't have any links to like a site, but i have a buddy that could built you a 4 link setup, i'm in texas though

 

Nah. More trying to find information so I can at least attempt to build my own someday.

basically all a four link is/does is a cradle around the rear carrier. it takes the torque transferred from the driveline to the rearend and redistributes it through the frame. this keeps the rear end in the proper place when under a load...

my suggestion when doing research on a four link is go back to where they came from...hot rodding...

popularhotrodding.com has some really good tech write-ups...

 

Alright. Thanks for that Savant. I guess my real question is then how did it go from hot-rodding, where everything seems to be low and/or fast, to 4-wheeling, where everything is more ground clearance and/or flex. But maybe I'll figure that out while looking around. Thanks again.

 

every sport eventually leads to another, the desert scene gives alot to slow 4wd crawling for example.

Ill grab some threads from pirate on link suspension and post them over here.

 

youre thinking of a truss dude...

 

No the way he describes it sounds like a link suspension to me. I see what you're saying though Gil.

The 4-link is designed to constrain the axle in the important ways (laterally and about the roll axis) but to allow as much freedom of movement in the other ways (up/down and about the driveline axis). Look at Pirate4x4.com on their bulletin boards. I think they have a 'link suspensions for dummies' thread that will really help you out. You can also try a google search. I think I may have some good bookmarks for you at home but I will have to let you know later on when I get back to my apartment.

 

he said it "cradles the rear carrier"

in no way does the actual four link "cradle" hes thinking of a truss with link tabs...

but thats neither here nor there...

 

You say tomato, I say to-mah-to.

im throwing the pirate one link thread in also for some interesting reading
One link?

 

i would argue, but its really to no gain. so to-mah-to on!

 

I misread what you said the second time. You're right it does sound more like a trussed axle than an actual 4-link. The action of moving the forces to the frame is more like the job of the 4-link (movement constraint).

 

When Xtreme4x4 did a link setup a while ago, they posted a 4 link calculator on thier website. Attached is the calculator in zip format...

 

so to-mae-to is actually right then huh??
