Engine Piston Kit
Cummins®

The Engine Piston Kit (part number 4089801) is a crucial component of an internal combustion engine. It consists of a set of pistons, which are cylindrical components that fit inside the engine cylinders and move up and down to convert the energy from fuel combustion into mechanical energy. The kit may also include piston rings, which seal the gap between the piston and cylinder wall to prevent oil from leaking into the combustion chamber. The pistons are typically made of aluminum alloy or cast iron and must be precisely machined to fit the engine block. They are designed to withstand high temperatures and pressures generated during operation without deforming or cracking. A damaged or worn piston can cause loss of power, increased fuel consumption, and even catastrophic engine failure. Therefore, it is essential to use a high-quality piston kit that meets manufacturer specifications for your particular vehicle make and model.
