Hello All,
Like the subject says what is the Effect/Importance of tieing the radius arms together. I've made provisionss into my radius arm brackets to do so. I'm just thinking of a simple crossbar that connects the radius arms and nothing into the stock trans cross member.

Thanks for the thoughts!

Educate me please. Why tie them together? Curious as I am new to all of this. I have only owned a-arm trucks up until now.

They have done it on long travel Ranger's for a while. One of the thought is to combat frame flex at the rear radius arm
mounts. I have seen it on a couple fullsize ttb's.

My $0.02 = depends on how you drive/use the thing or plan to. The theory behind it is a hard enough hit on one wheel (unseen boulder, sharp ledge at speed, etc.) and it'll push back on the wheel hard, which will roll the frame in at the arm mount. Seen it happen on rangers and full size. I'd take the time & do it personally.

I am going to do it to my
Bronco when I convert the AOD to the new C6. If it works out I plan to make the transmission rear mount, cross member and a skid plate work together.

Sooooooo if you look here at in tied together radius mounts.....

Probably the most annoying part of post roll repair was addressing the frame where the radius arms rolled under.

Ok I'll get on it-- what method did yo use Brian(Bryan)??

You can see in the picture my trans x-member I came off the rad arms and tied into that x-member.

I'll add that once the pass rad arm rolled in that bad it cause the beam to bind and bent that too. Alway wondered if I had them braced if any of it would have gave. Not sure if it was the roll that bent it if the 2' wall of dirt I went into causeing the roll that did it.

I guess in your pic I don't see where the radius arms are connected to each other??

They weren't tied together in that pic. Sounds like they are now after the rebuild.

In the pic above he's showing you how his pass. side radius arm folded under the frame in his roll & then saying fixing that frame fold in was the hardest/most annoying part of the re-build.

Sorry- Brian you have any pics of the modifications?

Here's what I came up with to tie the radius arms together -- kinda peer committee approved lol! 1 3/4" turned into sorta .250 wall via 2 pieces of .120 wall tubing because I'm cheap! Loses a pit of ground clearance but it's still 2" higher than the front differential- time will tell whether it gets ripped off all to hell.

I'm going to continue mine forward to the beam xmember as well as tie into the rear front hangers. Similar to Bray's setup....

Cool- that tells me I'm not too far off the mark and execution wise
