Extreme Landcruiser in socal was supposedly working on a jig to easily perform radius arm flips for customers. Every time I asked though it was put on hold. Last I spoke to them was about a year ago...

Cool thread and combined with the raised panhard resolves a lot of the issues caused by a tilted roll axis into oversteer on lifted 80s. Im not sure why there was so much false info about the axle end mounts moving being presented by people who clearly havent built any suspensions, but a little google search could probably square them away.
So what do you think - would you ever consider doing a radius arm flip on an 80? I've been toying with this idea for a while, but also like the 3-link kit being made by 4WU. Seems like this would be the easiest/cheapest option to gain a little more articulation and fix the handling issues associated with a lifted 80....
I would never do it. Its too close to the effort/work of a proper 3 link/panhard that has way more potential.
But theres no denying it fixes many of the problems people think are ALL associated with body roll.

too go one step further instead of flipping the stock radius arms what if you just replaced them with something liek the battlement fab arms. pretty much like what jodo did but the y-link upper and lower arms are parallel unlike jodo's jeep y-links arms which are offset. im just thinking of ways to get a little more flex and still keep from driving like s*** on the road!
Oh, chit.....
Be sure to check back in on this thread, as I'm anticipating a more thorough explanation requested and a debate.

you guys realize you could simple build an upper link tower and frame mount. Then bandsaw the front portion of the axle end radius arm off and be done with it if you are happy with how your truck drives but want a real 3 link/panhard for some reason.
DH, youve been brainwashed by some of the members who posted way back in this thread apparently. Wheres the connection between a 3link/panhard and s*** road manners?
Im just hoping any debate participants have actually built this stuff and then daily drive the kids to school and work all week. then load the family up with gear in it and goto the rubicon on the weekend.
Instead of preaching a false analogy of how the attachment point on the axle has no affect on geometry as seen on like page 6 or 7??

no not brainwashed at all i just dont have the knowledge to build a proper 3-link and get good road manners, i think a y-link radius arm set-up would be for one easier and could retain the stock mounting points as far as the frame of course you'd need new ones on the axle.
edit: and trust me i am not disputing the fact that a properly built 3-link can still retain very good road manners and insane articulation...ive seen all your builds. so when can i bring my bus over for a booger 3-link, ill have it filled with grannies for you!
Lol, grannies!!
Tim and australian fella both raised their radius arms and panhard and then reported feedback EXACTLY typical with the benefits of a flatter roll center and lower instant center. Yet theres a 'spike' and 'walkin eagle' convincing everyone the changes made have no affect, because nothing was changed geometry wise????
The radius arms act IDENTICAL to a lower and upper link combo, where the upper link is super short(in this case the space between the axle end radius arm bolt holes). You can plug the figures into the link calculator on pirate and see exactly what these guys did by raising the arms and the resulting improvement on suspension geometry.
Sorry, long winded...

I'm suprised no company's out there offer a 4 link "kit" Seems to be a demand
Claims to.
Tim's was a freakin monstrosity, so not a good barometer.
I don't know the "inch" lift, but it'd make a Slee'd 6" lift look short, and while it probably was an improvement, I followed and it didn't mitigate body roll.
Think you need a drink or twenty after that epic....with promises to report how that works out in mañana.
I'm not gonna debate crap because all I know is how NOT to do it...

kits for the 80 series in general are a small market. Get into specialized suspension components that require fab skills and that small market just shrank up like your balls jumping into the arctic ocean.
HAHA. Yeah your right. No way getting around having to do install/fab work. But if it where easy enough to install ppl could pay a indy shop to install and not have to pay tons of money. IDk. If I want one down the road I would likely just build it.

Finally documented pics of the radius arm flip. I will update pics in this thread. Vehicle was lifted 7" and is a daily driver.
It really is a great modification. Recommend it to those doing big lifts that don't want to go through the work or parts cost
to do the multi-link with coil overs. Each method has its advantages which depend on your usage and budget.
Is there a minimum amount of lift required to do the radius arm flip?
Pretty sure with the radius arm flip 4" minimum, while 5" works out very close to perfect. Raised panhard and high steer so everythings flat and parallel and you'll have a very good handling rig.

4" lift minimum for up travel clearance.
Since you are adding new brackets you can rotate them anywhere on the housing to accommodate your desired lift height.
5" seems to be the right place for keeping the radius arms in the proper arc.

Are you guys going to post up a thread for this or document the process somewhere? Also are the brackets something that can be bought or are they custom made?
