The Pertronix Ignitor II lobe sensor conversion kit replaces the dual breaker points inside Chrysler, Autolite, and Prestolite V8 distributors with a solid state module. It suits 1951 to 1971 Mopar V8 engines that used a dual point distributor. Adaptive dwell control keeps spark energy consistent, and the lobe sensor triggers off the distributor cam for a clean, points free setup under the stock cap.

FAQ
What does 91385LS fit?

What is a lobe sensor kit?
A lobe sensor kit triggers electronically off the distributor cam lobes rather than using a magnetic sleeve, which suits dual point distributors while keeping the stock appearance.

Yes, part 91385LS is designed for 12 volt negative ground systems.
Does it replace both sets of points?
Yes. The module replaces the dual point setup with a single maintenance free electronic trigger.
