PerTronix CU-121 Details

The original Ignitor module is ideal for restorations. Ignitor Module Kits are extremely easy to install and fit into your original distributor to maintain your stock look. No additional ignition box is required keeping a clean look under the hood. Ignitors are available for most distributors that came with mechanical breaker points and will cover AUTOMOTIVE, MARINE, INDUSTRIAL and AGRICULTURE applications.

Ignitor Electronic Ignition Conversion Kits have proven themselves in applications ranging from race cars to tractors. It is the number one Electronic Ignition Conversion Kit to replace original mechanical points. A Pertronix Points Conversion kit allows you to run a stock distributor while improving the reliability and performance of your ignition system. The Pertronix Ignitor kits simply bolt to the distributor in place of the points assembly and provides a much more accurate trigger signal. This improves the timing accuracy and prevents ‘points bounce’ at higher rpm. The electronic technology also improves the dwell control to improve the spark output of the coil resulting in a hotter spark at the spark plug. With this dependable, self-contained, maintenance free electronic ignition system you'll never replace your points again.

  • For the specified Cushman two-cylinder Truckster ignition-conversion application.
  • Fits inside the specified original distributor to maintain a stock-looking engine bay.
  • Electronic ignition conversion replaces mechanical breaker-point operation.
  • Self-contained design requires no additional ignition box.
  • Designed for straightforward installation in the matching distributor.
  • Eliminates routine breaker-point replacement for a lower-maintenance ignition setup.

I have an 1983 Cushman Truckster with an 18 HP OMC engine. The install was easy. However, I did have to drill out the lockdown screw hole. The distributor in my engine used a larger screw than the hole in the plate. It fired right up after installation and has never run this good. The instructions have a black and white photo and was hard to see what they were describing but was able to install with the written instructions. Took about 2 hours to install with running new wire protectors. Mine were falling apart when I pulled out the old wires.
