MAHLE 41844.030 Engine Piston Ring Set Oversize OE Replacement - 0.030

The MAHLE 41844.030 is an OE-grade engine piston ring set sized at +0.030" oversize, engineered to deliver reliable compression sealing, oil control, and reduced friction in rebuilt or re-bored engine applications. MAHLE is a globally recognized OEM supplier whose piston ring technology is driven directly by original equipment requirements, making these rings among the most technically refined replacement components available.

Key Features:

• +0.030" Oversize Bore Fitment — designed for engines bored 0.030" over standard to restore factory-spec cylinder clearances
• OE-Quality Materials — compression rings constructed from high-grade carbon steel with advanced surface treatments for durability and scuff resistance
• Pre-Lapped Design — rings are pre-lapped at the factory to seat immediately, virtually eliminating extended break-in time
• Optimized Ring Tension — material selection, coatings, and tension are engineered together to minimize friction and extend service life
• Barrel-Faced Top Compression Ring — promotes efficient compression sealing and reduces blow-by
• Reverse-Twist Intermediate Ring — provides superior groove-side sealing and enhanced cylinder wall contact
• Three-Piece Oil Control Ring Assembly — chrome-faced steel rails with an expander/spacer deliver precise oil scraping and drainage

MAHLE piston rings are developed using advanced simulation and computer engineering tools to reduce ring mass and friction while minimizing oil consumption — qualities that translate directly into improved engine efficiency and longer service life. The 41844.030 ring set is the trusted choice for professional engine builders seeking OEM-level quality in an oversize replacement application.
