Delta VS Radius Arms

[PeterTheBeater]

I think it’s just the geometry of new arms which allows more flex, with lifted everything else. There isn’t a particular single thing, and no alignment/bushings can fix it. Yes, old suspension hardware and bearings can exacerbate the problem, but it’s the geometry itself. Just like the jeeps and death wobble.

Also, I want to believe that some people on 3” 37s don’t need a DC, but I won’t believe them until I drive their truck

Don’t get me wrong, I love coming out to my truck and seeing that shiny DELTA plate under it, and telling myself I’ve got the best of the best $1500 arms, but they didn’t really do much for me, except needing a $400 DC

There's no one root cause for a death wobble. It could be many things but I would also check for cracks at the steering box as well as the radius arm mounts.

I have a friend that was chasing the same issue. checked everything the panhard bushing looked good as did everything else.
In the end he put new bushing in the Panhard and it fixed the issue.
This sh*t is now 30 years old and need to be replaced, I did all of mine as preventive maintenance no Death wobble

Aa a baseline, replace all bushings including engine&trannny mounts is a must.

I still haven't replaced the OEM body mounts yet on all my 80s

^^^^100 percent

Here you go-proof. 37s on 3.75" fronts & 4" rears (terrain tamer smart coils) and stock drive shafts

Ok, thanks guys! I missed some of the updates, but genuinely appreciate all the comments. Here is how I have proceeded:
1. New Panhard reduced Death Wobble a ton. Only getting about half as violent.
2. New 555 TREs. Better yet, now no Wobble on acceleration, but bad on hard braking.
3. Couldn't find a new stabilizer locally - left it off.
4. Put my 8724 on the ARB up front and installed White Knuckle sliders. (front springs are for extra weight - maybe too high unloaded for the Delta Arms??)
5. Toed out the alignment about 1/8"

Driving it after doing the toe out and zero death wobble!! Even without a steering stabilizer!!

So it was a combination of issues as many suggested.

OME stabilizer came in a few days later and is now installed.
Still no front sway bar, but I have the parts to put it on.
