Mahle Rings 4BT3.9/6BT5.9 Cummins Diesel Engine 17.3:1C/R Chrome Ring Set

This is a Mahle OE piston ring set specifically for Cummins 4BT and 6BT diesel engines. These rings are designed for a 17.3:1 compression ratio and feature a chrome surface for improved durability and performance.

Mahle is a well-known name in engine components, and this ring set is built to meet the demands of diesel applications. The chrome plating on the ring face helps reduce friction and wear, which can lead to a longer service life for your pistons and cylinder walls. This is a critical component when rebuilding or overhauling your engine, ensuring a proper seal for optimal compression and oil control.

When installing these rings, it's important to follow the manufacturer's recommended procedures to ensure a proper seal and break-in. This set is intended for use in engine rebuilds where a 17.3:1 compression ratio is specified.
