Default Four Link Questions,Question, Questions



The 65 Fargo is going to get the leaf springs from the 90 Chevy 1500 replaced with bags and a four link. I went pages and pages back in the forum section and found a few threads on four links but none that really answered my questions, in fact they added to my question.

Parallel ? Triangulated? Equal length? Unequal length? Yikes I'm leaning towards Triangulated, but don't know why
I'm not real comfortable with welding to the center section on the Chevy diff, but maybe the upper arms can be mounted just outboard of it?
How mush above and below the axle do the mounting brackets have to extend for proper leverage, my brain hurts Help

Don't give up, it's far too much fun once you can drive it.

I've always done triangulated. The more triangulation on the top links the better. When I was doing off road stuff we always ran the top links at 70% the length of the bottom links. It helps keep the pinion from pitching when it travels up and down, also keep the link parallel with each other. I know these rides we build here don't always have the most room. Hope this helps alittle

Supposedly with a triangulated 4 bar, you don't have to have a panhard or watts linkage to keep the rear centered.

If you have enough triangulation you don't have to.

Here is a double triangulated setup i did on my v8 samurai i built.
Also the longer the links the less are you get out of the axle when the suspension travels

Since you are doing bags, go triangulated or watts link. A panhard will move the body sideways when dropped and cause one tire to rub the body. Triangulated needs fewer parts over a watts.

I have ran panhards on my last 2 sedan because of space. I set them up so at ride height and laying on the ground the axle is as close to the same location. I make the panhards cross it's center point of the ark half way between up and down. If that makes sense
