Anyone know the brand of traction bars? Any good?

Have these traction bars I guess you call them on 1971 dart. Do they do any good or should I just replace it with factory stuff? Car used to be raced and then put back on the street and has sat for 20 years. I dont care for the way it twists the bottom shock bolt at all.

Shelby used traction bars to great effect. Sort of similar but much better build than these ones.
The lower spring plate had two ears welded on separate from the shock mount. The front mount bolted to the subframe and the front spring bolt. A bushing at each end of the traction bar allowed mounting the bars and prevented axle windup on the springs while not affecting the spring rate or ride quality.
