Mahle OE Cummins B 5.9L .040 03-04 17.1:1 CR HO Vin C and Eng ETH Piston Set (Set of 6)

These Mahle OE pistons are built to the original factory specifications for Cummins B 5.9L engines, specifically for the 2003-2004 model years with the HO (High Output) Vin C and Eng ETH configurations. They come 0.040 inch undersize, which is crucial if you're re-boring your cylinders to match. Mahle is a well-known name in engine components, and this set is designed to restore your engine's performance to its original operating parameters.

Each piston in this set is constructed from a durable aluminum alloy, chosen for its strength and ability to handle the high temperatures and pressures found in a diesel engine. The 17.1:1 compression ratio is maintained to ensure your engine runs efficiently and produces the power it was designed for. Mahle OE pistons are manufactured using advanced casting techniques to ensure precise dimensions and a smooth surface finish, which helps with proper ring seal and reduces friction. This attention to detail means they fit right and perform reliably, just like the original parts.

This set includes six pistons, enough for a complete engine rebuild. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to your vehicle's service manual for the correct installation procedures and specifications when rebuilding your engine.
