Poll: Do traction bars help out Mopar leaf springs or not
One thing that cannot be argued is traction bars use axle twist to apply pressure to the back tires. Does anyone not believe applying pressure to the back tires' aids in traction????
2nd thing is rear axle wants to spin like a propeller, lifting the passenger rear tire. And it would if it weren't bolted in. It's why, if not controlled, the black mark will be heavier on the drivers side. It's also why an open differential will almost always spin the passenger rear tire. Traction bars, unlike a pinion snubber, will keep the rear axle stable, help applying equal pressure.
Sure, once you change the springs, etc, then other things come into play.
