XJ traction bars

Any one using a traction bar on their XJ? I did a search and saw lots, but not on XJ's. I wrapped my springs pretty good this weekend, broke a rear d.shaft. They are 6.5" Rusty's mounted stock, now a nice "S" shape. In doing the search I've seen that most agree that the shackle end of the t bar should be at or near the front eye of the spring. I'd like to see pics of XJ's who have done that. The idea I'm toying with is making a mount and using my cage to support it from the top.

Thanks.

Look in the tech department. Bill Vista has a writeup on making an anti-wrap for his xj.

I built a old school lift block/traction bar thing that works fairly well. I know its not what your looking for but its alot simpler.

So let us know what it is and how it works.
ANyone have a link to the guy in tech that did it on his XJ? I am looking for ideas where to connect it as well on the body end.

I permanently deformed my Rusty's springs the first time out with them. They went from 4.5" of lift to -2" in about 5 minutes. My RE ones are holding up much better.

korda, you got any new ideas on this since the last time we talked about it?
My main question is if bringing it forward of the front spring mount(to the tranny skid I built) is going to bind any more than if we brought a crossmember over right at that mount and connected it there. I have searched and read and have found conflicting views. Anyone?

It looks like this only solid total height is 2" and I put 1 inch strap on the front going up over the top of the springs with a bolt through it but I deamed them not nescesary and cut them off.

I don't see a point in mounting the traction bar shackle in line with the leaf frame mount. That's the reason for the shackles. It doesn't need to travel in parallel directions like drag links and trac bars do. Just put it where ever you see would fit the best. whether you want it long or short, protecting the driveshaft, or tucked up out of the way. Just make sure you're shackle has enough movement in it where it's not going to limit your articulation.

The typical mount for the XJ i've seen is off of a T-case skid. Then there are a few that made custom mounts that bolts onto the floorpans. These were made to disperse the load throughtout a large area or else it would rip the floor right apart. However, coming through the floor from the cage, I think, is the best way to do it. _nicko_

Actually... forget about what I said about shackle placement. I just searched and found this, and it makes sense.

So you are saying that you agree that it should be mounted in line with teh forward spring hangers then.....right?
I agree based on reading that post. So, now comes the question- how the heck do you mount something back there? The unibody sucks to bolt and weld to. So shuld I fab up some crazy U shaped crossmember that bolts to the spring mounts as well?
Or I kind of like the idea of going to the floor pan with a big spreader plate to disperse the load.....any other options? THe other thing to consider is how to clearance the muffler in teh stock location.

Well, you know, that's the only reason I have 17 posts. Almost everything I've needed to know has been covered already.

And yes, now I agree the shackle should be in line with the front spring hanger. I guess my upcoming TB design will have a little change coming it's way.

This is from NAXJA. Check out the bottom of the page, and then the 2nd page has it installed. Looks a bit involved, but very nice to say the least.

Yeah, I saw that last night. Looks nice. The only thing I don't care for is the shackle is hanging down instead of pointing up. I think that will let the pinion rotate and limit flex. I did also read Billa's write up(that guy has too much time on his hands) I didn't know it was for his XJ though. Are heims any better or worse than poly bushings... than jonnie joints? Here's another thought. In conjuction with hanging a D60 off the rear, someone suggested reinforcing the front spring mounts. Make sense to me. So what about wacking off the sheet metal mounts and fabbing a Xmember from side to side incorporating cage tie in, spring mount and tbar mount. Obviously if the unibody wasn't already reinforced, it would need done to support the whole contraption. It would also act as a good frame stiffener. Granted, it would get close to the dshaft, but I think it could be done.

And please, no Rusty bashing until I find out if he'll warranty my springs.

Where on NAXJA did you find that? That is kind of what I have been talking about.
So all you experts out there, is it going to limit flex if the shackel hangs down rather than points up?

I am still curious if it affects the travel of the axle if the shacklle is mounted pointing up or pointing down. I have read a ton on this and some seem to think it does, but I would like to hear a definitive answer. Anyone?

Shackle above or below?

It makes no sense to talk about a shackle "pointing up" or "pointing down" since its two frickin strips of metal that are the same on both end. This however, is pointing up

If you say "shackles above" or "shackles below" the bar we know what you mean without a pic.

Climbing a hill the pinion wants to rotate up. The shackle will be stretched if its below the bar and compressed if its above the bar. Either way gets the job done (prevents pinion rotation), but below the bar gets the nod since it improves ground clearance. However, it is difficult to get correct location of the bar with the shackle below.

Orientation of the shackle does not affect articulation.

All that said, traction bars work in lots of different configurations, try it, break it, try it again.

Let the Rusty bashing begin!!! That bugger won't warranty his springs even though it's his prototype revolving shackles that caused them to twist in the first place.

Now, who has decent springs? RE, Tomken? I'd like good flex and a decent ride.

Were the rusty's springs the STS mil wraped ones? Those should be ok springs.

If the springs were run with a revolver type shackle, Bingo.. toss that.

The springs were not the STS springs and I was running a prototype revolving shackle that Rusty is working on. They are still in the testing stage. Thats why I'm alittle pissed that he isn't helping me out here. If I screwed up on my own, oh well, I can live with that. But I guess that's the price one pays for R&D. Anyway, screw leafsprings, I'm going coilover on the rear.
