Sealed Power R-10607.75MM Plasma-Moly Piston Ring Set 3.848 in. Bore .75MM Oversize

The Sealed Power R-10607.75MM is a Plasma-Moly Piston Ring Set designed for a single piston at a 3.848-inch bore with a .75MM oversize. Featuring top rings coated with the latest-generation plasma-molybdenum facing material, this set delivers fast break-in, superior oil control, and outstanding resistance to scuffing under demanding conditions.

Key Features:

• Plasma-moly coated top rings — barrel-shaped, ductile iron construction seals against blowby when the piston rocks in the bore
• Improved bond strength of the plasma-moly facing provides excellent resistance to flaking
• Controlled porosity coating results in improved top ring lubrication and faster break-in conformability to the cylinder bore surface
• Tapered secondary rings seal against the oil control ring's upper surface for excellent oil control
• 3-piece oil rings with stainless steel expanders provide proper tension without robbing horsepower
• Decreased friction and high melting point for exceptional resistance to scuffing at high RPM
• Exacting tolerances — meets or exceeds OEM specifications
• Recommended for street use, marine use, and racing applications where file fitting is not required
• Ring thicknesses: 1.2mm top / 1.2mm second / 2.5mm oil
• Sold as a single piston set
