Mahle OE Cummins B L4/ L6 020 w/ PC Eng Set Piston Set (Set of 6)

These Mahle OE pistons are made from a high-silicon aluminum alloy, a material chosen for its strength and ability to handle the heat and pressure found in Cummins B-series diesel engines. This specific set is designed for engines that require a 0.020 inch undersize piston, often used when re-boring cylinders to clean up wear or damage. The 'PC' in the description refers to the specific piston crown design, which is critical for proper combustion and performance in these engines.

Mahle is a well-known name in engine components, and this set is built to meet the original equipment specifications for Cummins B L4 and L6 diesel engines. Each piston in this set of six features a precisely machined skirt for smooth operation within the cylinder bore, minimizing friction and wear. The material composition and manufacturing tolerances are all geared towards ensuring reliable performance and longevity, especially in demanding diesel applications. You'll find these pistons are a solid option when rebuilding or overhauling your Cummins engine, aiming to restore its original power and efficiency.

When undertaking an engine rebuild with these pistons, it's important to ensure all related components are in good condition. This includes checking cylinder bore finish and taper, ensuring proper ring gap settings, and verifying piston-to-wall clearance according to Mahle's specifications. This set is not CARB approved and cannot be shipped to California.
