3503KD Ring Set 89.00mm for Wiseco Engine Piston Rings

Ring Set, 89.00mm for Wiseco

This ring set, 89.00mm bore size, is a replacement piston ring set for Wiseco 3503KD applications, designed to seal the combustion chamber and manage oil control in high-performance engines.

Overview

This Wiseco ring set is built to fit 89.00mm pistons for a range of performance engine builds, giving the piston the seal it needs to make compression and control oil. Each ring set covers the top, second, and oil control positions so a rebuild can be completed without hunting for individual rings. It is aimed at engine builders and riders who are refreshing a top end and want rings matched to the piston they already run.

Built For Performance

• Oversized ring set sized for an 89.00mm piston bore
• Includes the compression and oil control rings needed for one piston
• Manufactured for consistent tension and sealing under load
• Designed to hold compression in high-rpm performance applications
• Suited to rebuilds and top-end refreshes rather than original replacement

On-The-Job Use

• Top-end rebuilds on performance engines running oversized pistons
• Ring replacement when a piston is reused during a refresh
• Rebuilds where bore size has been confirmed with a measurement

Specs At A Glance

Good To Know

Q: How do I know this ring set fits my piston? A: Confirm the piston part number and the exact bore size before ordering, since ring sets are matched to a specific piston diameter and profile.

Q: Can I install these rings without checking ring end gap? A: Ring end gap should always be measured and set for your application before assembly so the rings seal correctly and avoid binding.

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