No idea... It showed it's arse at a really bad time (Week before world finals). So I put it in the trailer and haven't ran it since.

Just my

Better yet, bring it down here to the shop, I'll make ya one and sell every body else a copy. Want one Anthony???
If I had time I would. I'll pay good money to ensure it's fixed.

You make that. I will but it. Or whatever needs done. I have been thinking about Making control arms to control the caster. Was told that's huge in getting them to go straight.

I've got Rokmen lower control arms and the then one's I originally made still for uppers. This helped big time to fight road crown mostly. I don't think you're going to fix death wobble with caster. I think it'd be more of a bandaid, where you'd give it more 'return to center' force which could counter it. I'm not saying I'm right on this, that's just where my head goes.

I think the issue is keeping your axle centered and letting the drag link do it's thing. I think 90% of that issues comes from track bars being loose or flexing, another 5% to frame flex and alignment, and 5% to other.

If you're going to build a track bar, I get my stuff from RuffStuffSpecialties and have been very happy with everything I've gotten from them. And they're super cheap!

Just wanted to take a moment and say thank you for sharing this information gentlemen.
I need to work on my suspension once I get my auto swap done.

Just to summarize my opinions on this:


Your best bang for buck on these trucks is to take care of the track bar in one way or another.

That BD lower bearing for your steering gear box was a marginal increase in performance for me.
Adjustable control arms to fix caster was a marginal improvement for me.
Having tight ball joints, drag link, and tie rods played a big role.
Setting Toe-in correctly is always important.
Stiffer springs helped with control at higher speeds and corners, but definitely hurt ride quality a lot.
Make sure your sway bar is hooked up, and the end links aren't all worn out (that helps cornering and helps fight death wobble a little).
Balance your damn tires!
I have cheap shocks (can't justify QA1's), but having ones that actually work and aren't empty cylinders makes a big difference.

In a bind, while towing and having death wobble on the road, I lowered my front tire psi about 10psi and it went away. Replaced the track bar heim when I got home, aired back up, and it was fixed.
I've also fixed it when I was broke and in college by putting a shock in between the track bar and drag link. It worked surprisingly well.
These are both bandaids though. Obviously.

Good luck guys!

1.43... 2 years ago . If I could get this death wobble fixed i am ready to plant a good 60 and really lay down some good times I feel. Hopefully it will be addressed this year. All my 60's are 1.50-1.53.

I know some 2WD guys run it with heims so they can preload against the torque. Not sure if it matters as much on 4WD.

What does it cut 60 foot
Seems like that rear suspension would be really stiff with that many leaves left
