These are your slapper bars / traction bars / tramp rods etc.
Take a look at the first basic chrome pair. They fit in minutes, the U bolts just go over the leaf springs, one on each side of the axle. The extra leaf springs are no problem. When your axle starts to rotate and coil up, the bars oppose the rotation force.
Only problem you'll run into is when you have about 2" lowering blocks. I have a brand new set of tramp bars which I can't use because I have almost zero ground clearance.
Some states they are illegal. Who the hell knows why?
