Mahle MS Piston Set 04.5-07 Cummins 5.9L Forged Steel Monotherm 4.055 BR 4.724 STK 16.1 CR (6 Qty)

If you're rebuilding the engine in your 2004.5-2007 Cummins 5.9L 24V, getting the right pistons is crucial for reliable performance. This set from Mahle uses their Monotherm forged steel construction, which is a strong choice for demanding diesel applications. These pistons are built to handle the high pressures and temperatures common in these engines, offering a solid foundation for your rebuild.

Mahle's Monotherm pistons are forged from steel, a material known for its exceptional strength and durability, especially under heavy load. This particular set features a 4.055-inch bore and a 4.724-inch stroke, with a compression height of 2.804 inches. The piston itself weighs 1736 grams, and the set is designed for a 16.2:1 compression ratio, which is typical for these engines. The 1.575-inch pin size is also standard for this application. This robust construction means they're well-suited to withstand the rigors of continuous operation and potential performance modifications.

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 the manufacturer's installation instructions for proper fitment and assembly procedures to ensure the longevity of your engine build.
