What's the consensus on the new Rubicon Express "Builder Ball" joint?

This one:



The hole accepts 3/4" hardware. They are using either this one or their 5/8" model with in their Tri-Link kits. Basically they can eliminate the trackbar (panhard) with this setup. This joint is mounted on top of the diff with two links meeting at it and then the lowers are typical links.

Whomever is considering a 3 link rear for their 4 Runner, this might be an interesting option.

I heard they were coming out with a bigger one, but never saw the pictures or specs.

Not sure about the big one, but the smaller one's Steve uses on his lower control arms are sweet and flex great.

These items aren't the ones Steve is using. He's using the RE Superflex joint. These are much much larger. These are roughly 3"+ in diameter.

Correct, I was just stating the smaller ones that Steve is using are very nice units.

why does everyone want to ditch their panhard?

do they just not understand the benefits of having a panhard or what?

Do you have any constructive feedback on this RE joint? That's the question.

There is one benefit to having a panhard - that's to locate the axle from side to side If there are more benefits, we're all ears. Many 3 and 4 link designs don't require a panhard because their design inherently keeps the axle located under the vehicle.

other reasons would be:
panhard bar does not keep the axle perfectly centered through its full range of articulation. some have seen 1/2" movement to the passenger side with just a suspension lift. the tri-link cebby is refering to will take the place of the panhard, using the above joint ontop of the diff housing for lateral location of the axle. it would be stronger, maybe lighter, and for sure better (suspension geometry wise) than the stock panhard bar.

btw, looks like a quality piece, but i have no idea. looks nice though.

ok, ill start another thread on panhards to keep this one on topic.

as for the joint, i assume you are planning to use this joint for the center joint on the wishbone? if so, i would go for it over the standard RE joint. that single joint has to do a big job. it has to center the axle, and keep the axle from wrapping.

I think that is the whole purpose RE came out with this one. The standard RE joints aren't beefy enough to do all this stuff with one joint. They are using it in their tri-link systems now.

Even with this robust joint, there is still the gas tank to contend with.

leave the gas tank where it is and 3-link it

I don't think air shocks will work on our rigs. Too heavy, although I'd like to use them too for simplicity sake. Peter, please post the link to the panhard bar thread once you do it. Thanks,

Chris

I had heard that same thing. Mine will certainly not be any lightweight!

actually, now they have 2.5" and 3.0" airshocks, i highly doubt a 3rd gen is too heavy for a 3.0" airshock

You still should cut the back off of your Runner either way.
