http://www.campbellent.com/full%20size/shop%20pics0005.JPG Its a big pic so i dont want to directly add it for you dial ups. It seams like a good way to not have to run a track bar on the front end. Might get some bump steer though with regular steering setup. Just curious what everyone thinks of this set up.

Matt

To me it looks like its putting alot of pressure on the radius arm heim joint. Other then that i think the heims would wear out quickly due to their respective pressures in this setup, cant tell to well from this pic. i like the ingenuity though.....very interesting

It looks like your gonna max out and break the heims on those control arms. Shouldn't they be mounted vertically, not horizontally?

I have no idea what they will do. I was looking at pics on campells web page and came across that pic and found it interesting

Matt

Either it's just me or it looks like those joints are going to bind, snap, or cause a loss of flex. Or are the joints connected to the axle and rad. arm?

From the nearest i can tell is that one end is attached to the axle in the middle and one end is then attached to radius arm right before the bushing on the frame. I am assuming that by triangulating the bars it takes the side to side motion away instead of having a trac bar.

Matt

A trac-bar cancles the bump steer, as well as locating the front axle. That setup wouldn''t do that, but maybe that ram is for a full hydraulic steering , so that it mightn't have a drag link to cause bump steer in the first place.

You sure couldn't wrist an arm with that setup either.

What are you talking about it wouldnt locate the front axle. Its using 2 beams in a triangle. its going to center the axle just like a trac bar would. Who knows how strong it is though.

I think he was talking about the bumpsteer.:flipoff2:

I just talked to nick at campbell ent. Real nice guy! He told me they have been using this set up for a year on their ARCA. truck.
They havn't busted any heims and there is no "undue stress"
It's a ARCA. truck so stress is a relitive thing.
they sell the sys for any vehicle it's time and mat. you do tha measureing.
But there shop rate is only $50 bucks an hour.
The radius arms are boxed in bronco units and the tabs are steel.
the links are aluminum. Nick says they have not broken any yet.
more questions email him at

Sense the center links are handling side to side load that is the strongest way to mount them, and horizontally or virticle mounting doesnt effect how much flex they allow. If they were mounted verticly they would only have the press fit of the heim locating the axle :eek: this way they have the strength of the outer cage. And who cares if you can't rist the arms (and why couldnt you for that matter?) long radius arms can offer plenty of flex

Yup. You are absolutely correct. I didn't look at the picture carefully enough and thought that those middle two links ran from the axle, to the crossmember. I didn't see that they actually mount to the radius arms. My bad.

You could, but the arm wouldn't bend at the wrist. For the wrist to bend, the right end of axle has to move rearward, and the two links and left arm prevent that.

Essentially, this setup has one more link than is needed to locate the axle. In order to articulate, the whole axle has to move rearward, and the two links prevent that. If it doesn't bind,then it is only due to compression in the bushings. The pivot ends of the radius arms are forced outward by the links when crossed up.

You could remove either link, or even one radius arm (if you moved link pivot to frame) and the axle would still be located in all directions.

the wat this sys is set up the two links cancel any side movement
the c bushings have minimal flex as we all know but rubber would flex to much putting more stress on the links. the tabs for the links are welded to the arms and the arms have rod ends so theres no back movement. what this setup does is eliminate the bind of the trac bar in droop. and the off centering throughout the axels full range of motion. and if steering is set up right no bump steer.
