The OHC (Overhauled Core) designation indicates the magneto has been professionally overhauled, inspected, tested, and restored to approved service standards.

Built on Champion's proven Slick 4300 Series design, the 4371HP incorporates features that simplify installation and maintenance, including a lift-off housing that preserves internal timing during inspections, fully sealed bearings for enhanced durability, reduced electromagnetic interference (EMI), and a lightweight, compact construction. The 4371 model is an impulse-coupled, left-hand rotation magneto with a 20° lag angle, commonly used on compatible four-cylinder aircraft engines.
