Ring Set Components:

• Top Ring: Chrome-faced high temperature steel alloy with 0.8mm thickness for superior wear resistance and heat dissipation

Important Compatibility Information: Only Wiseco replacement ring sets are compatible with Wiseco pistons. The ring type (XA) and bore size (65.00mm) are stamped on the piston dome for easy identification. Ring styles cannot be interchanged between different types. Always verify the markings on your piston before ordering replacement rings.

Wiseco ring sets are manufactured to exact tolerances to ensure proper fit, compression, and long-lasting performance in demanding powersports applications.
