Cummins ISX QSX Dual Cam Upper Gasket Set | 4352145 | DOHC With Head Gasket

New FP Diesel (Federal-Mogul) upper engine gasket set for Cummins ISX / QSX dual-overhead-cam (DOHC) engines — replaces Cummins 4352145. This is a complete upper set that includes the head gasket along with the camshaft cover, manifold, thermostat, turbo, and fuel-housing gaskets plus the injector and HPI/XPI O-rings needed for a cylinder head R&R. Manufactured to meet or exceed OEM specifications.

Key Features:

• FP Diesel (Federal-Mogul) upper engine gasket set for Cummins ISX / QSX DOHC (dual-cam) engines
• Includes the head gasket — a complete upper set, not a head-gasket-less kit
• Includes camshaft cover, intake/exhaust manifold, thermostat, turbocharger, and fuel control housing gaskets plus injector and HPI/XPI O-ring seals
• Dual-cam (DOHC) specific — for CM570 / CM870 / CM871 ISX engines (not the single-cam SOHC ISX)
• Direct replacement for Cummins 4352145; manufactured to meet or exceed OEM specs

Specifications:

• Base part number: 4352145 (FP Diesel FP-4352145)
• Component type: Upper engine gasket set (includes head gasket)
• Condition: New
• Brand: FP Diesel (Federal-Mogul)
• Engine application: Cummins ISX / QSX, 15L, dual overhead cam (DOHC)
• Control modules: CM570 / CM870 / CM871
• Head gasket: included (Cummins 4299098)
• Also includes: camshaft cover gaskets, manifold gaskets, thermostat/turbo/fuel-housing gaskets, injector and HPI/XPI O-rings, cavity plugs, seals

Compatibility / Fitment:

• Cummins ISX / QSX 15L dual-overhead-cam (DOHC) engines with CM570, CM870, or CM871 controls
• Camshaft gate (critical): this is the dual-cam (DOHC) set — it will NOT fit single-overhead-cam (SOHC) ISX/QSX engines, which use a different upper set (e.g., 4376104 / 5406187). Confirm your engine has two camshafts before ordering
• Common in Freightliner, Kenworth, Peterbilt, and other Class 8 trucks running the DOHC ISX15
• Confirm your engine serial number / CPL before ordering, as ISX gasket sets vary by build
• Verify against the gasket set / head configuration being replaced

Conclusion:

The FP-4352145 is a new FP Diesel upper engine gasket set for Cummins ISX / QSX dual-overhead-cam (DOHC) engines, replacing Cummins 4352145. It includes the head gasket plus the camshaft cover, manifold, turbo, and injector seals for a complete cylinder head job — manufactured to OEM specifications. For single-cam (SOHC) ISX engines, use the SOHC set (4376104 / 5406187) instead.
