settle an arguement

i'm in a debate on another forum i am a member. it is regarding a traction bar.

a member posts look what i made & shows this.


another member starts ripping him appart how dangerous the setup is & causes stress on the spring thats not intended, blah blah.

i agreed it wasnt the best setup, but not the worst either. i did some research & found this. this is my general understaing of how it will react.



Single bar systems located below the springs

Single bars located below the springs actually help solve the axle wrap problem somewhat. Most rock crawlers avoid these setups because they don't want to reduce ground clearance, but they are fairly popular with mud boggers. These bars work by by putting the forward half of the spring under tension when axle wrap tries to occur. This tension fights the springs natural tendency to get shorter and turn into an "S" shape by pushing the axle housing back and pulling the springs straight. These bars are still not totally effective for axle wrap control because they depend on the spring to be rigid for triangulation, but they are more effective than bars located above the spring because they tend to straighten the spring when axle wrap occurs making the spring seem stiffer an generally reducing wrap by preventing the spring from going into an "S" shape.

These bars get more effective as the bottom mount for the bar gets lower, but they also lose more ground clearance as the bottom mount gets lower. These bars also somewhat limit articulation because the bar and the spring will swing through different arcs and bind.

what are your thoughts max? i dont want to put you in the middle of the debate, just trying to understand.

It is deffinately more involved than the description is making it out to be, but the points that are made are correct. There is nothing wrong (from a design standpoint) with what the guy did. will the spring bind slightly? Yes. Will it cause issues? No. Maybe in 50 years, the leafs will prematurely fail, but otherwise, someone is overly worried about a very small issue.

that was my general feeling as well, but the way the 2nd member was saying how dangerous it was & should never be driven on the street, made me 2nd guess myself.

thanks

Why not do them on both sides if your worried about springs failing prematurely or binding?

i'm not worried about it. another guy on the site basically made this truck out to be a death trap, just from the 1 picture i posted above. me & him went back & forth for a while, i figured i'd just ask max for my own knowledge.

Did the guy say that the only way to fix it was to use Ginormous Heim joints? lol.

That is true, a 1" heim or larger would make everything ay-okay!

There are places out there that make leaf spring floaters that allow you to have a 4-link while still using leafs, but they are more for racing classes that require you to use "stock type" springs. For what he is doing, they are fine.
