Art Morrison triangulated 4 link

I was going by this from that Ron Sutton link…

For the best adjustable rear suspension for road racing, track car, or AutoX car, is the adjustable 3-link, as it has the best articulation. The adjustable parallel 4-link will work well as long as the car doesn’t require a high degree of roll angle for the suspension to work.

Art Morrisons tri-five chassis has been proven to pull over a G... using the triangulated 4 bar... And this is nothing but a simple "replacement" chassis with somewhat improved suspension geometry. So unless you're going to be a competitive road racer, I don't see why this simple suspension wouldn't suit you just fine.

I am confusing a four link with a four bar. Sorry about that. I should know better than to post by now...

From the AME website:

4-Bar vs. 4-Link: A Tech Overview...
In a nutshell, a 4-link setup is best
suited to Drag Race or Pro Street type
vehicles where high horsepower engines
and large tires are being used. The 4-link
can be adjusted easily to compensate for
track conditions and control the amount of
“hit” the tire takes on the launch. And due
to the high kick-up of the frame rails,
modifications to the trunk and rear floor
are required—often times the rear seat
must be removed.
The 4-bar has longer, parallel bars and
a lower frame kick-up. It is ideally suited
to street and air spring suspension setups,
provides more latitude in setting ride
height and its polyurethane-bushed rod
ends make for a smoother, quieter ride. In
most installations the rear seat can be
retained, with little or no modifications the
seat itself. It’s neat for the street!

Don't confuse 4 BAR or PARALLEL 4 BAR with Triangulated 4 Bar -- they are COMPLETELY DIFFERENT configurations other than they use 4 bars...

Agreed. OP is talking about installing a parallel 4 bar in his car. He was told that the triangulated four bar is too complex for a novice to install.

He wrote and I quote:
"Scott with AME said the triangulated would be a tough install for a first timer. And after I read all the Ron Sutton stuff the parallel sounds like the way to go."

Not sure -- since I didn't go back to research -- who told him that (too difficult for a novice to install)... but that's really arbitrary. There are novices that shouldn't do ANYTHING and there are guys with pretty good brains and decent skills that can do a good job at most everything they touch.


I think ol' Jarhead is up to the task.


There's plenty of folks around here that would be happy to guide him if he needs it.

AME told him that. I have no reason to doubt that he is up to the task. I was more surprised that parallel 4 bar suspensions (aside from the Quadralink) are being recommended on this forum.
