Head Bolt Set 20-22 Ford 7.3L

The Head Bolt Set 20-22 Ford 7.3L by MAHLE ORIGINAL/CLEVITE is engineered for owners and technicians performing cylinder head work on sixth-generation Ford Super Duty trucks equipped with the PowerStroke 7.3-liter diesel engine. This fastener set addresses the critical demands of head gasket replacement, head removal, or performance builds where factory bolts have reached their service limit or require upgrade specifications. Proper head bolts are non-negotiable for engine integrity; undersized or corroded fasteners can lead to gasket failure, coolant leaks, and catastrophic engine damage.

MAHLE ORIGINAL/CLEVITE has manufactured OEM and OEM-equivalent fastening solutions for decades, and this head bolt set carries the precision required for 7.3L applications. These bolts utilize stretch-bolt technology—a controlled torque-and-turn or torque-yield specification—that ensures consistent clamp load distribution across the cylinder head surface. The exact material composition and thread geometry are calibrated to Ford's engineering standards, preventing bolt galling during installation while maintaining proper clamping force under extreme combustion pressures and thermal cycling. Installation requires a calibrated torque wrench and proper sequence to avoid warping the head or cracking the block.

Technicians rebuilding 2020–2022 Ford F-Series Super Duty trucks with the 7.3L gasoline engine will find this fastener set indispensable for any major head-off service. Whether you're addressing a head gasket failure, installing a performance cylinder head, or undertaking a full engine refresh, using OEM-spec replacement bolts protects your investment and ensures proper sealing and longevity. Always follow Ford's torque specifications and bolt-tightening sequence outlined in the service manual, and consider replacing bolts each time the head is removed to maintain structural integrity and prevent costly failures down the road.
