Piston Ring Set 4.105 Bore 1.0 1.0 2.0mm

The MAHLE PISTONS Piston Ring Set 4.105 Bore 1.0 x 1.0 x 2.0mm is a precision engine component designed for both high-performance and stock engine builds that require reliable compression sealing and oil control. This set is essential for serious rebuilds, whether restoring classic engines or upgrading modern street machines.

Featuring a bore diameter of 4.105 inches, this ring set includes dual compression rings (1.0mm each) and an oil control ring (2.0mm). The compression rings enhance gas sealing and minimize blow-by, which helps reduce crankcase pressure and maximize combustion efficiency. The oil control ring effectively manages oil return to the crankcase, preventing excessive oil consumption.

Ideal for builders and mechanics performing complete engine rebuilds on 4.105-inch bore blocks, this piston ring set is suitable for a range of applications from vintage muscle cars to modern performance vehicles. Proper installation requires careful honing to precise specifications and accurate measurement of ring end-gap for optimal performance.
