MSD's Ready-to-Run Pro-Billet Distributors for Chrysler engines are the perfect upgrade from breaker points or weak electronic ignitions. These distributors feature a maintenance-free magnetic pick-up that accurately triggers the built-in powerful ignition module. This module produces a high-output spark which improves combustion in the cylinder, resulting in quick starts, a smooth idle and great performance. Just beneath the race rotor is a mechanical advance assembly so a timing curve can easily be tailored to match your application. The QPQ coated shaft is guided by a sealed ball bearing assembly for stability and endurance while a vacuum advance canister helps increase economy on those long cruises. The Ready-to-Run Distributors are also a breeze to install. Simply drop it in the engine and connect three wires and you're ready-to-run to your favourite cruise! The front engine mount models are designed in a special small diameter housing to clear aftermarket heads and valve covers. A matching harness with a 3-pin Weathertight connector is supplied.

Cute but not durable
Color: Blue Octopus, Color: Blue Octopus
My dog LOVES the toy and was so excited to get it. It is so cute…but not durable like advertised. My chewer was able to rip a hole by the evening we received it. We like it…just not excited for the clean up

This is a BEAST for your beast! Best $27 I’ve ever spent! I spent that much money on toys in the past that have been destroyed in an hour.We’ve had it for 9 months and it still looks new.
