A balanced and matched set of 6 new Mahle pistons is brand new.
Mahle is the OEM (Original Equipment Manufacturer) for Cummins.
Why waste money on some no-name Asian knock-off brand?
Mahle OEM quality piston is available for close to the same price.
Fits 2003 - 2004.5 5.9 Liter 6BT 24 Valve Dodge Cummins i6 Turbo Diesel Engines with Vin Code: 'C' (8th Character of VIN #).
These fit applications including all pistons: 2003 - 2004.5 pickup truck, cutaway, tow-truck, and van applications.
This listing is for the standard pistons; please pay attention to the combustion bowls in the top center of the pistons (see pictures).
You must match the bowls on your pistons clips.
This is a complete set of 6 pistons with dolly and pins.
Mahle pistons feature ni-resist top grooves to control groove wear.
The set of 6 is balanced for smooth engine operation.
The M124 piston material (used in these pistons) is a highly evolved 'Eutectic Recording Material', containing approximately 12% silicon for excellent strength and thermal expansion properties.
For diesel engines, the Eutectic Recording Material is chosen because it adheres better with ring ground ring or groove inserts used to strengthen and better support piston rings in high performance/high load diesel applications.
The Eutectic Recording material with Mahle piston ring groove inserts performs better than a forged material that doesn't hold the insert very well.
Mahle pins are made of high-strength steel to meet structural requirements to prevent pin breakage or deflection.
They are case hardened to provide long-lasting wear surfaces.
A high degree of dimensional control and surface finish are the ultimate requirements for strength and long life.
