Victor Plasma-Moly Piston Ring Set Bore

The Victor Plasma-Moly Piston Ring Set is a complete engine piston ring set (also called a piston ring kit) for engine rebuilds and performance builds. Each set uses a plasma-moly faced top compression ring. The facing is made for heat resistance, good oil retention and reliable cylinder wall sealing. The product line is available in several bore sizes and engine configurations.

Key Features:

• Plasma-moly top ring facing: The molybdenum coating is bonded to the ring face. It resists heat, flaking and scuffing.
• Controlled porosity: The porous facing holds oil on the ring face. This improves top ring lubrication and helps the ring conform to the cylinder wall during break-in.
• Complete ring set: The set includes a top compression ring, a second compression ring and an oil control ring.
• Reduced friction and wear: Plasma-moly facings help control blow-by and oil consumption. They also support long service life.
• Versatile use: Plasma-moly ring designs are commonly used in street, performance, racing and marine engine builds.

Choose the variant that matches your engine's bore size. Check the bore, ring width and engine type on each part number's listing before you order.
