Traction bars can be made to work very well. Those are actually the better design since they have the leaf spring plate integral to the traction bars. The problem is, they are for a different application other than Mopar. They are too short for one thing. Where they are clamped to the front spring segment should extend all the way under the front spring eye bolt with a rubber snubber and the shock stud is very obviously at the wrong angle. If those two problems were addressed, they would plant the rear axle hard enough to remove some asphalt. While it's true Mopar used pinion snubbers, traction bars can work equally well and better if properly set up.
