Piston Ring Set 3.2475 3/32 3/32 3/16 3/16

The Piston Ring Set 3.2475 3/32 3/32 3/16 3/16 by HASTINGS is an essential engine rebuild component engineered for precision fit and reliable compression sealing. This ring set is designed for mechanics and engine builders who demand OEM-quality performance during top-end overhauls, rebuilds, or performance engine builds. Proper piston ring specification—including bore diameter, ring thickness, and gap tolerances—directly impacts combustion efficiency, blow-by control, and engine longevity, making correct part selection critical for any serious restoration or modification project.

This ring set features a 3.2475-inch bore diameter with precisely engineered compression ring and oil-control ring dimensions (3/32-inch top and second ring thickness, 3/16-inch oil ring thickness). The multi-piece design ensures optimal ring gap clearance, radial tension, and axial stability within the piston grooves, minimizing friction while maintaining effective seal pressure against the cylinder wall. HASTINGS rings are manufactured to strict tolerances using premium cast iron and steel materials, resisting scuffing, micro-welding, and wear during high-temperature combustion cycles and reducing unburned fuel blow-by into the crankcase.

This piston ring set is ideal for anyone rebuilding engines in the 3.2475-inch bore range, including classic muscle cars, light trucks, and vintage domestic powerplants. Proper installation requires honing the cylinder to the correct surface finish, accurate ring gap measurement, and careful assembly to prevent binding or excessive clearance. Verify bore diameter, engine block specifications, and OEM service bulletins before purchase to ensure compatibility; using the correct ring set prevents catastrophic compression loss, oil consumption, and engine damage during break-in and sustained operation.
