Off-road roll-centers
Off-road roll-centers
(OP)
This is sorta a 2 part question, okay mabey more...
...On a typical trophy truck, or really any other off-road 4-linked vehicle, the upper triangulated bars are, typically, "run" wide on the chassis and come to either a single point (ie. wishbone style 3-link) or close to each other on the rear end housing.
So, question one. Why would you want the roll-center to be "attached" to a moving part of the suspension? Especially one that moves as much as 36" or even more. Why not mount the bars wide at the rear end and narrow at the chassis?
Second, would an off-road truck benefit from a lower roll-center in the rear? What would be the problem with running a Satchell link or other similar system to lower said roll-center?
I know, always with the off-road questions, but it seems so "Black art" ish.

RE: Off-road roll-centers
I'm thinking that lower roll centers will mean more roll, and that in general that will leave slightly less suspension travel remaining on one side or the other to cope with bumps.
