Fitment FAQ
Will this part fit my specific model and year?
This voltage regulator rectifier is intended for Engine / HP / CC. It is best matched to original part number(s) 5GT-81960-00-00, 5BN-81960-00-00. Key physical/spec details from the product data include Voltage: 12V, Installation Hole Spacing: 62 mm / 2.44", Installation Hole Diameter: 6 mm / 0.23". Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. Match your original part number to 5GT-81960-00-00, 5BN-81960-00-00 before purchase. For this voltage regulator rectifier, also compare the OEM number, plug shape, pin count, mounting-hole distance, heat-sink style, and AC/DC charging-system type. This is especially important for Yamaha Grizzly/Kodiak models because similar model names can use different parts by year or trim.
What models or situations does this part not fit?
Do not order this voltage regulator rectifier for machines outside the listed compatibility, or for units with different pin counts, plug shapes, AC/DC system types, or mounting-hole spacing. If your original part number does not cross-reference with 5GT-81960-00-00, 5BN-81960-00-00, treat the fitment as unconfirmed. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the OEM number, plug shape, pin count, mounting-hole distance, heat-sink style, and AC/DC charging-system type. Confirm OEM/cross-reference number(s): 5GT-81960-00-00, 5BN-81960-00-00. Recheck listed specs such as Voltage: 12V, Installation Hole Spacing: 62 mm / 2.44", Installation Hole Diameter: 6 mm / 0.23". If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
