Good To Know

Q: How do I know this ring set fits my piston? A: Match the 48.25mm bore size and the 1900CS part number to your existing piston and application before ordering. Ring end gap should always be checked during assembly.

Q: Is this an original equipment part? A: This is an aftermarket ring set for Wiseco applications and is not an original brand product. Confirm your piston and bore specifications before installation.

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