Product Description

The Cummins ISLE Upper Engine Gasket Set 4089758 is a precision-engineered sealing solution designed for compatible Cummins ISLE diesel engines. Catalog references identify 4089758 as an upper engine gasket set for ISLE applications, with other parts references associating the same number with ISC and ISL engine platforms.

The 4089758 upper gasket set is intended for engine maintenance, repair and overhaul work where multiple upper-engine sealing components are required. The set can include essential gaskets, O-rings, sealing washers and related components used around the cylinder head and upper engine assemblies.

The Cummins 4089758 gasket set is commonly associated with ISLE/ISC/ISL engine applications. Because engine configurations and production specifications can vary, buyers should verify the engine model and ESN before ordering to ensure the correct gasket-set configuration.

For genuine Cummins parts sourcing and wholesale orders, please provide your Engine Serial Number (ESN), engine model or existing part number. Our team can verify the application and confirm the appropriate gasket set.
