Overview

These exhaust valve gaskets are replacement seals for the power valve system on Arctic Cat ZR 440 Sno-Pro sleds built between 1998 and 2001. They seal the valve to the cylinder, keeping exhaust pressure where it belongs and preventing the leaks that cause rough running and lost top-end response. Cross-referenced to OEM numbers 3005-226 and 3005-283, they suit riders and shops performing routine top-end service on the ZR 440 Sno-Pro.

Specs At A Glance

Good To Know

Q: How many gaskets come with this set? A: The set is intended to service the exhaust valve assembly on the ZR 440 Sno-Pro. Check the quantity listed before ordering if you are doing both cylinders at once.

Q: Should these gaskets be reused after disassembly? A: No, exhaust valve gaskets should be replaced any time the valve is removed. Reusing a compressed gasket risks leaks and inconsistent valve operation.

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