Speedmaster PCE306.1036 4.000" Bore Plasma Moly Piston Ring Set - Zero Gap

The Speedmaster PCE306.1036 is a complete piston ring set engineered for small-block engines with a 4.000" bore specification. Featuring a 1.5-1.5-3mm ring thickness profile, this set incorporates plasma moly coating for enhanced durability and reduced friction during engine operation. The zero gap design ensures precise fitment and consistent compression characteristics, making it an essential component for engine rebuilding and performance applications.

These piston rings are designed for use in high-performance and stock engine rebuilds where reliable sealing and long-term durability are critical. The plasma moly surface treatment provides superior wear resistance compared to traditional cast iron rings, promoting extended engine life and stable ring-to-bore contact. Suitable for racing, street performance, and general engine restoration projects, this ring set delivers the precision engineering expected from quality aftermarket performance components.
