Piston Ring Set 94.00mm Bore 1.2 1.5 3.0mm

The Hastings Piston Ring Set 94.00mm Bore (1.2 x 1.5 x 3.0mm) is a precision engine component engineered for eight-cylinder applications requiring exact bore diameter compatibility. This complete piston ring kit delivers the compression sealing and blow-by control critical to engine performance, fuel efficiency, and longevity across both stock rebuilds and performance applications.

The ring set employs standard tension architecture with chrome-plated steel construction, a time-proven design that balances durability with minimal friction. The 1.2mm top ring, 1.5mm second ring, and 3.0mm oil ring combination is dimensioned to achieve proper ring gap sealing at the 94mm bore diameter while managing thermal expansion during extended operation. This stacking ensures consistent combustion chamber pressure retention and effective oil control—critical variables that directly influence fuel consumption, emissions, and engine wear patterns.

Technicians and engine builders select this Hastings piston ring set when performing complete engine overhauls, restoring original equipment specifications, or refreshing high-mileage powerplants. The chrome finish resists scoring and corrosion during installation and break-in, reducing installation risk. This is a drop-in solution for eight-cylinder engines with a 94.00mm piston bore—verify your engine's exact bore diameter and ring groove dimensions before ordering to ensure proper fit and performance.
