spring plate traction bars

I built a ladder bar setup. It's been ok, but some trouble. First off, a weld broke loose, bolt sheared, and axle tube spun. Got the axle tube straightened up and welded. Then an actual peice of my axle tube tore out, leaving about a 2" diameter hole. Got that fixed. Buddy of mine whose a good mech., says I should try some traction bars that he has. They're the kind that mount on the spring plate on each side. Would these screw up my flex? After searching, it seems that everybody uses ladder bars on their CJ's.

Ladder bars are good for drag cars and trucks pulling a sled. Build one like this.

I use the dual bar setup from Warrior called Traction Barz. They work quite well for me. I don't do any wild rock crawling but you do have the option of disconnecting them in the middle for more freedom. 2 square tubes one inside the other. I substituted the supplied bolts for quick disco pins.

This is the kinda whiny crap I would expect to see in the JK forum. We drive rough riding, leaking, gas guzzling CJ's. Rattle can it and throw it in your Jeep.

Stick a 2x4 behind your gas pedal.

Usually I don't hear that much damage to an axle from a trac. bar. At this point if you don't want to change your driving style then its time to upgrade to a bigger axle that has sufficient strength that can handle it. Dana 60 or a ford 9" will have sufficient tube thickness to handle what you have (assuming you have a 4.2, and the model 20 is what you are destroying).

The last thing you want to do is put "traction bars" on. And this is coming from somebody who drag races their CJ....

This is basically what I had (which I can still put back on with some work). Exact same bar, except I did away with the u-bolts and welded it to my axle tube and built a cross peice in the front to mount my shackle to instead of attaching to the skid plate.

My bud has the kind that bolt to the spring plates on both sides. So the spring plate type is a bad idea? That's all I really need to know. Thanks for the responses!

Gotcha, thanks, and you ARE talking about the kind that bolt to your spring plates, right? Sorry, I'm not real clear on the names of these traction aid devices!

What you really want, is about 8" of distance between the upper and lower bar, and the mount attached to the axle housing tubes. Anything narrower and the bar will not have the "leverage" to counteract torque.

I have the same basic setup as 82jeepcj7 does. Mines just a simple bar I made from 1" pipe and some old shackle bushings I had laying around. I never ramped it with and without, but can do over 1000 with it.
I think it's even more important to weld the pumpkin to the tubes on an AMC 20 when installing a traction bar. The pumpkin is still trying to rotate upwards, but instead of having the cushion of the springs as it tries to twist, the bar will hold the axle tubes solidly in place as the pumpkin torques upwards. No more give to it.

Ok, you've convinced me to go back to my track bar. Started working on it yesterday. I am going to u bolt it to my axle instead of weld it, though. That way it will slip if I put it in a real bind. My axle tubes are welded up now, so no more slipped tubes. Thanks for the replies. Best Jeep forum around!
