These new replacemnet couplers are far more rigid than the original units to allow more accurate engine timing and reduced drive wear. Fits both two and four pin drives.

Fits both 4&8 cylinder magnetos for the following models:
- Sprint Mag I, Sprint Mag II, Sprint Mag III
- Super Mag II, Super Mag III, Super Mag IV
