With that design, wouldnt it be more expensive and more weight then a 3 link? side to side roll during a turn isnt a big issue if its only during major flex, am i wrong?, Couldnt you do a custom setup like trckmagik but angle the shocks? this would add pressure against the side to side to minimalize it, but still have flex? i might be wrong.

From what i see and what makes a lil sense is to still go one link, with coils and do angled out shocks (longtravel?) to assist in counter side steer. or is that a 3 link?

so the axle would still move side to side but it would stay straight. is that what you are saying?

 

[SuperEx91]

i am pretty sure that would bind. if you seperate them too much, you will lose ground clearance.

 

[everythintech]

are you refering to my post? no the axle wouldnt move side to side, the angled shocks keep it stable. and long travel shocks give you all the travel you will need. if you are refering to mine....

Now how would it work if you replaced the panhard bar for a Watts linkage or a Mumford linkage?

 

[everythintech]

any pics of that?

i'm gonna figure this out. it WILL go fast.

It can work, there is no doubt about that. It is not too geometrically different than Chevy's(?) Torque tube suspension. And rear steer can actually be a good thing if its set up right and predictable (Ford Focus, Mazda 6, etc). But designing it yourself, you just have to be sure of all the pros and cons, and minimize the cons. Another con is that you don't have much choice on where the pivot goes, as it has to be near the rear of the transfer case or you'll have driveshaft problems or a really low pivot. If that length link works well to counter squat/antisquat great (and I'd think it should be fine w/ a 4 door) but if it doesn't what do you do?

Yeah that could work, but you're halfway to a 3 link.

I guess what I'm saying is I'd rather put all the time designing a rear setup into a nice wishbone 3 link.

i like that two link w/ watts linkage. and to me the simpler it is the better. I like this thread. there will be an outcome of a very very good suspension system that is lower in budget and will work out awesome!

That's why I was wondering if a double one link might work. Just trying to think outside the box. Basically use the grader ball design to attain the desired mass ammounts of flex, but also mount another reversed with the one link on top of the axle, like a wishbone. I would think they would have to be equal in geometric dimensions, but am not sure if they need to be.

Thoughts?

all that is, is a trianlulated 4 link. think about it instead of two links meeting in the center you have one solid V link, same idea and geometry

As I was sitting in the hot tub and drinking brain juice, AKA, MGD, I realized that and think a 3 link wishbone or 4 link will better suit what I want.

However, here's another thought to throw arround. What if I just do a reverse wristed radius arm design like my front?

As far far as the mumsford and watts, it isn't practical to the cheap, functional or easy design I was looking for.

Diff, I sent this link to a buddy who custom makes panhard bar kits and a making 4 link set ups now for Ford F-150s. I'm waiting on his feedback...

I don't think I've ever seen a rear radius arm setup on any RWD vehicle. I'm guessing because of anti-squat issues.

its been done before. I remember seeing it on pirate4x4

 

[Trckmagik]

I dont get any side to side movement with my 3 link. Couldnt be happier with the decision to do it.

 

[Exploderpilot]

look at the control arms on the rear end of most trophy trucks that run parallel to the shocks. i don't see why that wouldn't work with the grader ball as sort of a composite 3 link.
