Wiseco Piston Ring Set 94.00mm (3701XR)

The Wiseco 3701XR is a 4-stroke piston ring set sized for a 94.00mm cylinder bore, supplied per piston with the correct top, second, and oil rings to restore compression, sealing, and oil control on a Wiseco top-end rebuild. Wiseco develops and tests its ring sets specifically for its own forged pistons, so they hold their geometry and seal under high-RPM and race conditions.

Important compatibility note
