Lets see your Traction bars

[tRustyK5]

How? They were able to rotate individually to prevent them fighting each other...yet were pivoted at the shackle end with the same 3/4" bolt.

The shackle end never broke...

What would have helped would have been way softer bushing material at the diff end to allow for some of the differences in arc. That bar had delrin bushings...great material but way too firm. Softer bushing would have allowed some wrap though. Bandaid part IME, no matter the price, or how pretty.

383...not bolts, alloy pins.

The alloy pins are stronger than bolts? And of which grade?

Anyway, like I mentioned, it sounds like those leaves offer VERY little resistance to axle wrap and hence rely heavily on the traction bar. 1/2" bolts are pretty small for a link that has to resist the the torque running through the axle, typical is more like 9/16"-1 1/4"

I can't recall anymore...it's been 7 years or so ago already. They didn't fail immediately, and I did intentionally beat the hell out of it for testing purposes (side step clutch at 3K, dry pavement, 40's). then again, they're kind of sposed to take a beating.

9/16"-1 1/4" would be better, but to be honest if I'm gonna spend that kind of coin on brackets, hardware, etc etc I'm just gonna link it up and forget about it. Oh yeah...that's pretty much my plan.

I'm with you on the links, it can be done for relatively cheap and as I said before its one of the most worthwhile mods I've done to my truck.


Really, adding an anti-wrap bar to a very soft leaf sprung suspension is a half a$$ed way of building a three link suspension. The two leaves represent the lowers, the traction bar is the upper and the bushings at each end of the springs provide the side/side stability that a track bar otherwise would.

Marv Springer (who hardly ever comes around here anymore) came up with a really cool idea of a link suspension that used half of a leaf spring for two of the links and suspended the weight of the buggy.

Basically it had two tubing/joint type links and then a single leaf spring cut in half (half on each side, it's still a four link) that resisted the torque running through the axle and also held the weight of his buggy.

sounds like a 1/4 elliptical suspension

Generally, a 1/4 elliptic would be a four link suspension that uses a half leaf spring on each side to suspend the weight of the truck.

IIRC, Marv's idea actually used the half springs as both the upper links and the springs themselves. Two lower links and two 1/2 springs that served dual purpose as upper links and as the springs that support the weight of the truck.

hey NOAHROB on one end you have bushings but what is that on the other end on the far right? looks like some kind of baring. and could you just use bushings insted? thanks.

BTW im using alot of your guys pics in another thread right now titled "anti axle wrap". hope thats cool. it explains alot of stuff i never knew and 38377K5 is a life saver in there. i asked a lot of stupid questions but what the he!! right? dont ask you dont know right
