OK... Been Brain storming many ideas for traction bars... I Know... Scary...

Well there is the traditional bar (top Image) Which would push up on the frame infront of the rear axle lifting the front end. Then there is my Idea (bottom image) which pulls down on the frame behind the rear axle lifting the front axle... Question is... Which lifts the front LESS... the pivot point is the axle... I know that by making the bars in front of the rear axle shorter you would take away some of the leverage( closer to the pivot point) I am thinking that short bars behind the axle would provide even less lift. I know its not the normal way of thinking but...

You may put the shackle in a bind running it backwards like that.

 

why are you going in reverse in your pics?

 

That is the direction that the axle housing would rotate...

Like diesel-n-dust said, you run a pretty good chance of binding the shackle that way, as your axle travels up, the shackle wants to move it back, but your traction bar idea wants to push it forwards, so binding is gonna happen.

Your other problem with doing that is that you want the front end to lift (more so in a rwd car, but even in a 4wd truck it makes sense), the more front end lift you get, the more weight you'll get transferring to the rear end, and lets face it, the front end has plenty of weight on it already. Now a good 4-Bar setup runs with a link on top and on the bottom of the axle, which when properly setup and adjusted will give you perfect straight launches, without any impossibility of axle wrap...but thats the advantage of not running leafs I guess.

 

no offense, but if something like that worked, then i think it would have been thought of before. although theres a first time for everything. to me, the 2nd image (your idea) would push the front acle up more, b/c the weight of the truck going back, and it smomentum forward seems like that would push it up more. idk how to exaplin it, but thats my opinion.

 

'Cause we all know that EVEYTHING that could be thought of has been...

 

hence the "theres a first time for everything" quote.

--but that set up would almost be like a spring shooting the front up. at least thats how i picture it working. also, i dont think the frame of any vehicle sticks out far enough past the rear wheels for that to work properly.

 

These truck have plenty of frame left to do that with. I wouldn't touch it, stick with the original design.
