Piston Ring Set 2.953 1.2 1.5 2.8mm

The Hastings Piston Ring Set 2.953 1.2 1.5 2.8mm (MPN 2C4640) is a drop-in piston ring kit engineered for 4-cylinder engines with 2.953-inch bore specifications. This standard tension ring set features a chrome-plated steel construction designed to provide reliable compression sealing and oil control in production and rebuilt engine applications where precise ring dimensions and proven OEM-equivalent performance are essential.

The ring set combines three critical components: a 1.2mm compression ring, a 1.5mm secondary compression ring, and a 2.8mm oil control ring. This three-ring configuration delivers effective blow-by control while managing oil consumption within design parameters. Chrome plating provides corrosion resistance and extended ring life, particularly important in marine environments or engines exposed to harsh operating conditions. The standard tension specification ensures compatibility with original equipment cylinder wall finishes and piston groove dimensions without requiring special installation tools or machine work.

This piston ring set is suited for engine builders, machine shops, and mechanics performing complete engine rebuilds on 4-cylinder platforms where OEM specification rings are required. Hastings rings are recognized across the automotive rebuilding industry for precision manufacturing and consistent performance in both daily-driver and high-mileage engine applications. The 2.953-inch bore size covers a range of small-displacement 4-cylinder engines commonly found in compact and mid-size vehicles across multiple manufacturer lines.

When selecting replacement piston rings, matching the exact bore diameter and ring thickness specifications to the original equipment is critical for proper sealing and engine longevity. This kit provides a complete set ready for installation without requiring additional components or modifications, making it a straightforward choice for full engine rebuilds and top-end overhauls on compatible 4-cylinder engines.
