CR Piston Ring Set 3.820 Bore 1/16 1/16 3/16

The TOTAL SEAL CR Piston Ring Set 3.820 Bore 1/16 1/16 3/16 (part number CRL5899-25) is a precision-engineered piston ring kit designed for classic race engines requiring drop-in compatibility and optimized low-tension performance. Built with plasma moly coating, this six-cylinder ring set delivers the compression sealing and blow-by control necessary for sustained high-RPM operation while minimizing friction losses that would otherwise rob horsepower.

The 3.820-inch bore diameter with 1/16-inch top and second ring thickness and 3/16-inch oil ring thickness represents a proven geometry for small-displacement six-cylinder builds. The low-tension design reduces parasitic drag on the crankshaft while the plasma moly surface treatment resists scuffing and extends ring life under demanding combustion conditions. This kit arrives ready to install on compatible bores—no custom fitting required. The drop-in specification means you avoid the labor and expense of ring end-gap filing and bore-specific modifications.

TOTAL SEAL piston rings are favored by engine builders and vintage racers who prioritize reliable combustion sealing and predictable performance in competition and street-driven classic engines. This set suits builders restoring or upgrading original equipment or preparing a six-cylinder engine for consistent track duty where ring durability and compression retention matter. The specifications are particularly suited to naturally aspirated, carbureted builds where traditional ring designs have proven track records.

Ring selection directly impacts cylinder sealing efficiency and oil consumption—specifications that define the difference between a well-tuned classic engine and one that burns oil and loses power. The 3.820-bore standard width and the plasma moly coating establish this kit as a straightforward replacement or upgrade path for six-cylinder classic race platforms where bore diameter and ring thickness are critical matching points.
