Piston Ring Set 3.796 Bore 1.0 1.0 2.0mm

The Piston Ring Set 3.796 Bore 1.0 1.0 2.0mm (MPN: 3801MS-112) from MAHLE PISTONS is designed for mechanics and engine builders who require OEM-grade ring performance in high-revving or modified powerplants. This precision piston ring set is essential for replacing worn or damaged rings that can lead to loss of compression and blow-by control, which directly affects fuel economy, oil consumption, and power output.

Featuring a 3.796-inch bore diameter, this ring set includes a three-piece configuration: two compression rings (1.0mm each) and one oil control ring (2.0mm). MAHLE's manufacturing precision ensures consistent ring gap, radial thickness, and face coating, which are critical for effective gas sealing, reduced friction, and enhanced wear characteristics. The dual 1.0mm compression rings are optimized for low-to-mid-range blowdown, while the 2.0mm oil ring effectively scrapes cylinder walls and returns excess lubricant to the sump.

Engine builders working on 3.796-inch bore engines, commonly found in mid-displacement domestic and import platforms, rely on MAHLE's consistency to achieve proper compression ratios and minimize combustion blow-by after cylinder honing. Proper ring selection is crucial for cylinder sealing and longevity, making this ring set an excellent choice for both stock engine rebuilds and performance builds.
