Mahle Rings Perf Gas Nitrid Steel Oil Ring 4.0945in x 3.0MM .127inRW Plain Ring Set (48 Qty Bulk)

The 3.0mm wide oil ring, made from nitrided steel, is a key component in this Mahle OE performance ring set. This specific width and material choice are crucial for effective oil control in high-performance gasoline engines. Nitriding the steel surface hardens it and improves its resistance to wear, which is essential for maintaining a good seal against the cylinder wall over time, especially under demanding operating conditions.

This bulk set includes 48 individual oil ring sets, making it suitable for engine builders or shops working on multiple engines. Mahle OE is known for producing well-built engine components that meet or exceed original equipment specifications. The precision manufacturing ensures that each ring fits right and performs as expected, contributing to efficient combustion and proper lubrication. The 4.0945-inch bore size is a critical measurement for ensuring a proper seal within the cylinder, preventing oil blow-by and maintaining compression.

When rebuilding or modifying a performance gasoline engine, selecting the right piston rings is vital for overall engine health and performance. This Mahle OE set offers a robust solution for oil control, designed to handle the stresses of performance applications. Always refer to your engine's specific service manual for detailed installation procedures and torque specifications to ensure optimal performance and longevity.
