1973 Duster Need Lots Of Help

air shocks r decent but not good if your going performance, my dad had those on his 70 challenger for one night, it was a factory 4406 pack car and it was blueprinted and all and when he hit the gas the first time the back end dropped and he lost traction quickly, dont ask me how that what he said, but if i were you id get some qa1 shocks, yes their expensive but omg they r nice, im getting some for my car, its got a ladder bar setup and coil overs so mine would be different from yours but qa1 r nice shocks
