Mahle Rings Performance Grey Iron BT-10UF 4.0846in x 2.0MM .178in RW Chrome Ring Set

This Mahle OE Piston Ring Set features a 2.0mm top ring thickness and a 0.178-inch oil ring width, designed for a 4.0846-inch bore. The chrome plating on the top ring is a key detail, as it helps to reduce friction and wear against the cylinder wall, contributing to a longer service life for both the rings and the pistons. These rings are built from grey iron, a material known for its good wear characteristics and ability to handle heat effectively.

When you're rebuilding an engine, proper ring seal is critical for performance and longevity. This set is engineered to provide a solid seal between the piston and cylinder wall, which is essential for maintaining compression and controlling oil consumption. The specific dimensions and materials used in this set are intended to meet the demands of engine rebuilding, ensuring that your engine runs smoothly and efficiently after the work is done.
