New Hartzell PowerUp Magneto ES4300 & ES6300 Series

FAA-PMA Aircraft Magnetos for Lycoming, Continental, and Franklin Engines

Upgrade your ignition system with Hartzell PowerUp ES4300 and ES6300 series magnetos. FAA-PMA approved direct replacements for legacy Slick magnetos. Available in both impulse-coupled and non-impulse configurations for 4- and 6-cylinder piston engines, these new aircraft magnetos deliver stronger spark, easier cold starts, and long service life.

Engineered with performance improvements:

• Impulse Coupling: Single-piece hub design with no rivets. No SBs or ADs
• Capacitor: Internally grounded lead with square insulator and stud base for improved durability and installation accuracy
• Coil: Thicker insulation for higher spark output; thicker lamination plates resist deformation during assembly
• Breaker Points: Clamp-up force on metal frame with improved spring to eliminate point bounce and reduce point drift over service life
• Block Assembly: Arc suppression ribs reduce misfires; geometric asymmetry prevents incorrect installation
• Distributor Gear: Monel construction for superior arc erosion resistance; heat-staked electrode for mechanical stability

Includes 1-year warranty. Core return necessary to receive core credit.
