if u have somethig to beat upo, then go for it, but until then, i wouldnt...

 

Your traction bar idea should work as I have successfully created a traction bar concept like your drawing. My Super Duty is lowered and I had two options for my exhaust - a stack or out in front of the tire. I opted for the front of the rear diff and had no realistic space for a traction bar in front. But - the rear mounting point of my setup is level with the front, so as the suspension moves up and back nothing binds. If you have access to a way to put weight in the back of your truck, mach some mounting point ideas, measure loaded and unloaded lengths to the differential mounting points and you should be on track.

 

Got pics?

 

I'll get some pics for ya this weekened.

 

Bobby,

I think you will find that in your design, there will be no weight transfer to the rear end, to obtain traction.

Essentially, the rear will "squat" as a result of the axle being "lifted" away from traction. Effectively, you would now have 2 axles (Front and Rear) with no weight for traction.

I'll try to explain.

Inertia transfers weight naturally to the rear end of an accelerating vehicle. This tends to "lift" the front, and "squat" the rear.

In your first example, the physics involved would "push" the rear axle toward the traction surface, therefore taking advantage of the inertia shift, providing better traction to the rear, while also attempting to place more load on the front axle.

This would have the effect of resisting the "squat" normally incurred by the weight transfer, and allowing an additional "pushing force" downward, to where traction exists.

In your second example, the physics involved would actually "lift" the rear axle away from the traction surface, increasing the "squat" and not taking advantage of the inertia shift, thereby lowering rear traction, and simultaneously lowering weight on the front end...

Hope this helps.
