Reed Valve Assembly for Ski-Doo

This reed valve assembly functions as a direct replacement intake component for Ski-Doo snowmobile engines and carries the OEM cross-reference 420924519.

It suits riders servicing their own snowmobile or shops handling routine top-end maintenance.

Specs At A Glance

Good To Know

Q: How do I know if my reed valve needs replacing? A: Common signs include rough idling, hard starting, and a loss of low-end power on your Ski-Doo 550. Inspect the petals for cracks, chips, or gaps against the cage before ordering.

Q: Does this assembly include the reed cage and petals together? A: Yes, this listing is for a complete reed valve assembly rather than loose petals alone. Confirm your model year and engine size match the fitment listed before purchase.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
