Snubber for Duster

If you go to the track, leave it at home. It wont do anything positive.
Really? Won’t help with the keeping the pinion angle at the ideal (angle) on launch? Won’t help with forcing the tires into the pavement at all? Assist with the cars rear raising all the while? Of all the suspension books on how to properly set up the “factory” Chrysler leaf spring rear for drag racing Ive never read that the pinion snubber won’t do anything positive. We are talking using factory parts correct?
