Piston Ring Set 4.350 Bore 1.5 1.5 3.0mm

The Piston Ring Set 4.350 Bore 1.5 1.5 3.0mm by MAHLE PISTONS is a premium compression and oil control ring package designed for high-performance engine builds. This product is ideal for serious engine builders or mechanics undertaking a full bottom-end rebuild, ensuring proper combustion sealing and oil management in demanding applications.

This piston ring set features a 4.350-inch bore diameter with a two-piece compression ring stack (1.5mm top ring, 1.5mm second ring) and a 3.0mm oil control ring configuration. The dual compression rings work together to seal combustion pressure while minimizing blowby, which is critical for maintaining cylinder pressure and fuel economy. The three-millimeter oil ring effectively prevents excessive oil consumption by scraping lubricant from cylinder walls while maintaining a protective film.

Engine rebuilders, machine shops, and performance enthusiasts will find this piston ring set particularly beneficial when completing a full-bore overbore or sleeve situation requiring a 4.350-inch bore diameter. MAHLE's reputation for precision manufacturing ensures consistent ring gap and proper seating against the piston groove, reducing friction and extending engine life.
