The SPI 09-730 OEM-style piston kit is designed for dependable engine rebuilding and replacement applications where a standard-size piston assembly is required. This kit includes a piston and matching rings with a Teflon coating, providing a practical replacement solution for restoring proper piston and ring function during an engine overhaul. Its OEM-style design supports compatibility with applications that call for original-equipment-style components and standard piston specifications.
The included Teflon-coated rings are designed to support smooth piston movement and effective sealing within the cylinder. Proper ring installation and piston-to-cylinder fit are essential for maintaining compression, managing oil control, and promoting reliable engine operation. Always verify the application, bore specification, ring configuration, and manufacturer installation procedures before assembly to ensure the kit is suitable for the intended engine.
Supplied as a kit, the SPI 09-730 offers a convenient option for professional technicians, machine shops, and do-it-yourself rebuilders handling piston replacement or engine restoration work. Use this standard piston kit when the existing cylinder condition and service measurements confirm that a standard-size replacement is appropriate. Inspect all related components, follow recommended assembly practices, and use the applicable service information for clearances, lubrication, and break-in procedures.
