This may seam like a basic question but could someone explain the difference between a 2-link, 4-link, bags on leaves? What does a cantilever do the differences between a triangulated 4-lin and a parallel 4-link and anything i may have forgotten? I think it would be good just to have this on the forum for everyone and I have no idea. We might even be able to make it a sticky. Thanks

2link-1 link on each side, hooked to the axle solidly. Changes pinion angle drastically. Still, a good setup, but many people dont recommend them.

parallel 4link-bars mound parallel, and mount to the axle. A panhard bar must be used. Small side to side movement from the panhard making its circle. minimal pinion angle change

triangulated 4link-Ususally requires a fuel cell, but no use of the panhard bar since the triangulated bars take out side to side movement. minimum pinion angle change

cantilever-mis used term to describe a leverage setup in most cases. A leverage system is bags mounted on a lever, to get more lift than the actual bag provides.

You guys forgot about six links. I don't know the difference so i can't explain it.

Not a truck, but here is a parallel 4-link, the bar on the rearend going left to right on the frame is the panhard bar, that centers the rearend.


Here's a triangulated 4-link, the upper bars from a triangle, they support while also not allowing side to side movement, but they also take up more room.

Any more info on six links?
6 link is just a parallel 4 link in the front, and a 2 link (not solidly mounted to the axle) in the back, the bags are mounted on the back 2 links in a lever setup where their lift is like 2:1 ..... if the bag is over the axle it's a 1:1 ratio of lift.



Here's a 3-link .. usually used on minis .. while it looks sort of like a triangulated 4 link, the top bar is all one piece

does anyone has a picture of a 2-link? what are the pro's and cons of each different setup? the more links the smoother the ride?

This is a Chevy factory 2-link from the early 70s ... in a bag setup the airbag would go in place of the spring .. the further forward it is from the axle the more lift you would get ... if you look, the 2-link is fixed solid at the axle but pivots at the front. ... the more points of articulation you have the better off you are.

I was thinking of a six link with the parrellel four but then it has the trianglulated top as well. Would make one hell of a strong set up.

huh? a 6-link could be a parallel or a triangulated 4-link .. just depends on what you want, as said before though the triangulated 4-link usually requires moving the gas tank.

I've seen one around where it is not moved. Instead of the upper links being together on the pumpkin they are spread out on the axle and meet together on the frame. Anywho, just wondering.
