Wiseco Piston Kit with Gaskets, 66.00 mm, Honda (PK1121)

The Wiseco PK1121 Piston Kit with Gaskets provides the core components needed for a complete engine piston replacement. Designed for select Honda applications, this kit includes pistons, piston rings, wrist pins, circlips, and a top-end gasket kit for one complete engine. It is a practical solution for rebuilding the top end while using components engineered for dependable fit and performance.
Wiseco PK1121 replacement rings must match the ring style specified for the piston. Wiseco ring types are not interchangeable; for example, CD rings cannot be substituted for LC rings. The correct replacement ring style is stamped on the piston dome. Common markings include “C” for XC, “G” for XG, and “H” for XH. Verify the marking on the piston before ordering replacement rings or beginning assembly.
This Honda piston kit features a 66.00 mm piston size and is supplied with the essential top-end components included by Wiseco. Cylinder sleeves are not included and must be purchased separately when required for the application. Confirm vehicle fitment, piston markings, and engine specifications before installation to ensure the kit is appropriate for the intended rebuild. Follow the engine manufacturer’s service procedures and Wiseco installation guidelines for proper clearance, ring orientation, and final assembly.
