1909CD Ring Set for Wiseco 48.50mm

Ring Set for Wiseco

This piston ring set is sized at 48.50mm and seals combustion pressure while controlling oil on the matching piston bore.

Overview

The 48.50mm ring set provides the sealing rings needed for a top-end service on the specified piston size. Each ring in this ring set is built to hold compression and manage oil along the cylinder wall. Engine builders use this ring set when replacing worn rings during a rebuild.

Built For Performance

• 48.50mm bore size matches the specified piston application
• Ring set configuration covers the required sealing positions
• Material chosen for heat and wear resistance in small bore engines
• Designed to seat against the cylinder wall for consistent compression
• Ring faces machined for even contact and reduced blow-by

Fits These Machines

• for Wiseco piston applications specifying a 48.50mm ring set

On-The-Job Use

• Top-end rebuilds on 48.50mm bore engines
• Replacing worn rings during a piston service
• Compression restoration on small bore two-stroke and four-stroke engines
• Routine maintenance requiring exact bore sizing

Good To Know

Q: How do I confirm this ring set suits my piston? A: Match the 48.50mm bore size and ring set configuration to your piston before ordering. Part number 1909CD should also appear in your engine or piston documentation.

Q: When should rings be replaced? A: Replace them when compression drops, oil use rises, or a rebuild is already underway. Ring gaps and cylinder condition should be checked at the same time.

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