    First, what is this type of suspension called? And what are the pros and cons of that arrangement vs dual A-arms?

    currently have trailing arms but am having issues with the axles binding at full plunge. I’m about to have to make some minor changes to the suspension to accommodate a more interesting engine and am considering ditching the trailing arms and going with something that will take care of the plunge issues and give me some camber control. I like the dual A-arm idea because it would also give me some toe adjustment, but i’m reluctAnt because i just don’t see many dual a-arm setups in full size buggies and am assuming there’s a reason why.

    advice and opinions woild be appreciated

    There are loads of options to look at. The Edge have a full hub to hub you could look at as a starting place.

    The pic you linked to is just a standard RZR three link. Basically a trailing arm with two control links. Simple, effective. They induce toe as they move through the travel. It's not much but it's there. The lower link in the back is also a tender spot - they like to drag and get destroyed by rocks and such.

    The Canned Ham X3 and the Mini Raptor use a modified three link - the hub in the back is a steerable piece so it controls toe.

    Dual a-arm cars are stout as can be and done right work very well. I think a lot of the reason behind a large boxed trailing arm like you see on so many off road vehicles is simplicity. ONE bullet proof piece for the suspension instead of a pair of arms or a bunch of links.

    I can't recall if his had it or not - go look at JD66's build. I think he may have had rear a-arms. Also check flyerrider's build - that thing was a-arms all around and worked very nicely - and brought the off road cops right to camp at Ocotillo with TALON behind the wheel (you hellion you!).

    Take your time to learn and find the option that will best fit your needs but also you fit your buggy. ☺

    I always referred to it as a three link but when I tried to research it all I ever turned up were solid axle builds. I do see your point about the lower link being a weak point, and the simplicity of a trailing arm makes sense. I think I'll lean toward dual arms. That seems more stout and the drag point shouldn't be so much a problem with a beefy, boxed lower arm.
