I’ve been thinking the same for my 40. I put a single 80 radius arm on the rear of my SOA 40 as a sort of traction bar with a shackle at the body, and it works surprisingly well.

Love this idea. Can you mount them on the top side of the axle for more clearance?

I will try, just need to see where they land. I am going to try to collect the rest of my parts over the next few months and do some mock up before. And try to do the install in Feb. I will do that in my build thread for Lynchburg Lemonade in the 40 section. Unless you guys want to see it here too?? Not sure it is that hard core.
Coilovers may not be the best on that. I feel that factory radius arms don't flex enough that coilovers are really necessary, but it would be worth it for packaging maybe. 10" coilovers would probably be all you need.

Thats my thought. Not a lot of room to get a coil and shock in there. I have already ordered my bracket to mount the arms. I plan to play around with shock placement and figure what mounts to buy while everything is on sale this weekend. I am only aiming for a 10" 2.0 CO, not sure a 12" will fit.
Which bracket did you go with? Rampt?

I bought these to start. He is going to get me 4 of the ones that are more round for the axle tube. My plan is to mock them up and then fill in and gusset them. Thought it would be quicker than starting from scratch. If I can mount them on top of the axle I will, if not then under it will be.

And something like this for the shock tower.

I have some left over pan hard brackets from other projects, so I will use those, a Slee DIY adjustable pan hard bar kit, and cut that to fit, need it to be the same length as the drag link to help with bump steer. I have used this kit before and it works well.

I need to bring home my FJ62 front housing and clean up the brackets off it and prep for installation. I plan to add some gussets to it as well and a skid plate/bash plate on the front.
RCV will sell me just the long side inner shaft and I will re-use the RCV's from the current 40 axle and use all the other parts, as it already has FJ60 series outers on it.
All of this work to get rid of 1.5" wheel spacers and hope for a better ride.
Radius Arm mount reinforcement plates
Radius Arm mount reinforcement plates After ripping my radius mounts arms off the axle I made some reinforcement plates. The second batch was made so that the bottom was above the oem plate a little so your not welding 100% upside down. Weld on, may require some grinding. They are designed to...

This will be about how I imagine the radius arm mounts. Looks like it should work out well with angles. I also may do a cut and turn on the housing to rotate the pinion up and get more caster.

I am sure they make them in house. Guess they use a 70 series front axle.

Hey @matzell , this is a huge threadjack and I’m happy to delete and put elsewhere, but I had a question for you and those following this thread; I saw where you gave some advice on pirate many years ago concerning beadlocks, and I was looking do someone with experience to give some advice - basically, are they needed for wheeling, and do they work when you have to drive a long distance to get to the wheeling?
I suppose wheeling needs better defined, but basically the SW Colorado type, not necessarily the Rubicon type or the KOH type for sure.
I’ve searched the forum for this and don’t seem to come up with much.
Any advice is appreciated.
Hoping to move to bigger tires and want to make the right investment if I need to change wheels.

Here is what I’ve been working on

5 link radius arm on 12” RaceRunners, I “think” likely the only one out there. And this gets street driven at highway speeds

Wow! I am late to this party... I have been doing the exact same thing this winter.. I already had a 60 axle in the front with the 60 steering box. In the end, I decided to copy the 80 suspension with 10" coilovers. I know this setup will not work for everyone. But, mine is a family rig. We don't do crazy buggie stuff anyway. I made my own radius arms because I didn't want them to hang so low like the 80.
Different sort of radius setup from mine. If you look, my lower bars are parallel and separate from each other. Have you cycled that? If the swing angle geometry isn’t just right the radius setups can bind up, HARD
Copy that. Yes, I did cycle it before final welding. And yes, you are correct. It starts to bind at the 5" mark. Which is the limit of my coilover. I agree, it would not work for a longer travel setup. Do you have a thread on the front suspension? Or a pic or 2 without tires on.
Best I can do right now. Panhard is in the fairly standard location, 40 has very minimal lift with this setup
