The 5-year warranty on P-Line gearboxes is activated through online registration. C-Line gearboxes come with a two-year warranty which can be extended to three years free of charge by registering online within 12 months of the initial purchase date.

For legal reasons, we can no longer sell a separate warranty extension to 5 years for the C-Line.
