For a drag only (or any application for that matter), you might want to look into Global West and the Del-a-lum bushings. They are a greasable delrin inner and aluminum outer bushing that allows for smooth movement of the control arm against the shaft. I have them in my bracket car and they are really sweet, totally worth the money. After all, smooth consistent motion is what is preferred for a drag car. Sometimes, the poly and rubber bushings can be described as sticky, not ideal for suspension tuning on a drag car.
