Piston Ring Set - 4.190 Bore 1.0 1.0 2.0mm

The Piston Ring Set - 4.190 Bore 1.0 1.0 2.0mm from MAHLE PISTONS is an essential component for any high-performance engine rebuild. This set is perfect for mechanics and engine builders who are freshening up a long-block, assembling a stroker, or restoring a vintage muscle car. Proper piston ring selection is crucial for maintaining compression retention and controlling blow-by.

Engineered to match a 4.190-inch bore diameter, this precision ring set features a classic three-ring configuration: a 1.0mm top compression ring, a 1.0mm second compression ring, and a 2.0mm oil control ring. This design optimizes ring tension and sealing performance while effectively managing oil consumption in various applications, including street and moderate boost setups. MAHLE's commitment to manufacturing precision ensures consistent gap clearance and radial force, which are critical for proper ring seating during initial engine operation.

This piston ring set is ideal for use in naturally aspirated or modestly turbocharged engines within the 4.190-inch bore family, including late-model Chevy big-blocks. With a total weight of 0.6 lbs, it is lightweight for easy handling while providing the sealing integrity that MAHLE has been known for since 1920. Mechanics and engine builders will find this set to be a reliable choice for their performance needs.
