• Service needs on older breaker-point and distributor ignition systems

Installation Notes and Tips

Verify distributor cap style and rotor mount type before installation. This rotor uses a push-on design, so the fit should be checked for secure seating on the distributor shaft. Confirm vehicle-specific ignition configuration, including Canada emissions notes, clip-on cap requirements, breaker point ignition, or transmission control switch applications where listed. Use the vehicle fitment data to match the correct year, make, and model before service.

Quality Assurance

Standard Ignition supplies ignition service parts for a wide range of OE-style repair applications. JR-75 is built to meet the needs of distributor ignition maintenance on confirmed fitments, including Toyota, Suzuki, Geo, Chevrolet, and related import vehicles.
