ProX Piston Ring Set - Yamaha Phazer

The ProX Piston Ring Set for Yamaha Phazer is an engine piston ring set for 2-stroke snowmobile rebuilds. It gives the cylinder the sealing it needs to restore compression and keep the engine running consistently. Use it as a replacement piston ring set during a top-end rebuild or routine engine maintenance.

Key Features:

• Made to OEM specifications: ProX piston rings are produced by OEM factories to exact specifications.
• Trusted ring makers: ProX sources from well-known manufacturers such as Rikken Japan, TP and NPR.
• Keystone ring design: The rings use an internally notched, keystone profile for dependable sealing.
• Compatible with common bore types: They can be used in cast iron bores, nickel ceramic plated (Nikasil) bores, boron composite bores and electrofusion bores.
• Chrome bore note: If the cylinder is an OEM unit with chrome bores, ProX supplies a different ring, as found in the ProX piston kit.

ProX engineers its pistons and piston components for precise fitment and durability, and builds them to meet or exceed OEM specifications. Choose the correct variant for your bore when you order.
