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.

I'd remove that traction bar.
Strongly consider a pair of new shock plates. It's hard to tell from the photo if that's a home made thing or just a repair.
Check the driveshaft angles and install pinion angle shims as needed. IIRC need 2.5" wide shims.

How much more than that you need to do will depend on its future use.
