What are the pros and cons of a rear 3 link (panhard bar) suspension setup? versus a 4 link or leafs

I'm more specifically thinking about a general trail rig, full body that sees road miles

I've seen them on desert truck and moon buggys but cant think of the last time i saw them on a full body rig
 
I have a rear 3 link on mine. 43s, heavy, doubler, Ls power. It’s holding up well so far.

I know my 3 link is compromised a little due to not going in the cab for shocks and other packaging issues

That's weird.

Roll steer usually sucks on those suspensions.

i may have only seen it once :laughing:

i just remember the super long drop on the frame side for the panhard bar to make it flat
 
Depends some on what the front suspension is. Does the front have a panhard or is it a symmetrical suspension? (Triangulated 4 link, IFS).

Biggest cons are strength and side to side movement.

Pros are not leafs, clearance, and sometimes side to side movement.

3 link front with panhard,

upper link on the front vs the rear would be opposite sides of the vehicle but the panhard bar could be mounted either way, symmetrical or opposite

My understanding is the have the frame end of the panhards be on the same side is the preferred option when doing dual 3-links. It helps keep the body from yawing with respect to the wheels.

A feature of 3-links is how the upper link and panhard react to drive torque.

Not a trophy truck per se but recreational prerunner it’s common. They market them as short course suspension typically. When full body, fuel tank, etc are at play

Gotchu.
I have seen some of those.
 
Giant Motorsports does a daily driver link setup that runs a 3 link with panhard bar. Get the panhard as long as possible and flat at ride height and it works good. I have 4 or 5 friends with desert trucks that run that setup without any issues.
 
TTMotorsports I just looked at their daily driver kit. What does the air shock do?

That's his old DD link setup where he didn't run upper links so that allowed articulation and controlled axle wrap. They didn't work very well and multiple customers changed and added a single upper link so he redesigned his kit to run the 3 link setup now.

oh i get ya, basically a radius arm rear

the idea of having some torque dampening has some merit tho

weird they still show the pics with the little air shocks

Wild, I thought it was some extra travel thing. “Daily driver kit” told me it didn’t go in the bed or something and it would pivot to that little shock to give it 2 more inches of travel. Couldn’t be more wrong lol
 
Yeah to do the full under bed setup you'll have to do something like I am on my OBS f-150 build. Cantilever coilovers with bronco gas tank under uncut stock bed.
