Poll: Do traction bars help out Mopar leaf springs or not

Street or strip doesen´t say but on the strip in 1976 still and another couple years, this was enought to keep control of a brutal high revving Hemi. Time was in the 9.7 at 140 mph.
Personally I dont think it is a question for the street. We don´t race on the streets anymore, do we?..
