Detailed description

The HGS4298 head gasket set is engineered for upper-engine resealing when the cylinder head is removed. It addresses the critical sealing surfaces between the cylinder head and engine block, helping restore compression and control fluid transfer across the engine’s top end. This part number is listed for Ford Transit-150, Transit-250, Transit-350, Transit-350 HD, F-150, and Mustang applications, with fitment notes that vary by model year and head-bolt requirement. This part cross-references MAHLE HS54990 and HS26543PT for the same application.

For Ford F-150 and Ford Mustang service, the HGS4298 provides a premium sealing solution for engines that need a complete gasket refresh during head work. The set is intended for applications where accurate sealing of intake, exhaust, valve cover, camshaft, thermostat, and related upper-engine interfaces is required.

What it is used for

• Replacing worn head gaskets after cylinder head removal
• Restoring sealing after overheating or coolant loss
• Addressing oil leaks from upper-engine gasket surfaces
• Correcting combustion pressure loss from damaged sealing surfaces
• Refreshing multiple top-end seals during engine rebuild work

Installation notes and tips

Verify engine code, bore size, and head-bolt requirements before installation. Fitment includes 2011-2015 Ford Mustang, 2013-2014 Ford F-150, and 2015-2019 Ford Transit applications, with some listings marked w/o head bolts. Follow factory torque procedures and replace torque-to-yield head bolts when required by the engine specification.
