MAHLE B Piston Ring Set

The MAHLE B Piston Ring Set is an engine piston ring set for engine rebuilds and repairs. Piston rings seal the combustion chamber, control oil on the cylinder wall, and move heat from the piston to the cylinder wall. Replacing worn rings can restore compression, reduce oil consumption, and bring back smooth, efficient engine performance.

Key Features:

• Compression and oil control: Each set is built to seal combustion pressure and keep oil from reaching the combustion chamber.
• OE-style engineering: MAHLE is a leading original equipment supplier of pistons, rings and engine components to automakers worldwide.
• Durable ring materials: Piston rings are made from wear-resistant alloys, and many carry surface treatments for long service life.
• Consistent quality: The rings are manufactured to tight tolerances for dependable seating and ring-to-groove fit.
• Ready for rebuilds: Suited to engine overhauls, cylinder re-sleeving and piston replacement.

For best results, install the rings with properly honed cylinder walls and check ring end gap and side clearance against the engine manufacturer's specifications. Choose the correct part number for your engine and bore size.
