Distributor Advance Springs
Optimises spark advance to maximise power and prevent pre-ignition (pinging) with Negative Pressure Supercharging and hot air induction
Negative Supercharging advance springs fit ONLY 1957-91 Chrysler made points or electronic distributors
Negative Supercharging advance springs produce a unique advance curve that gradually increases the ignition timing from idle to peak rpm. This maximises power and prevents pre-ignition (pinging) with the ultra fast burn produced by Negative Pressure Supercharging and hot air induction. The advance springs fit ONLY Chrysler made points or electronic distributors.
Therefore, compare the photos of the Chrysler made distributor and advance weights to your distributor and select one of the following options.

WARNING: DO NOT use remanufactured electronic distributors
