Federal Mogul 26552 PT PermaTorque Head Gasket Set

The Federal Mogul (Fel-Pro) HS 26552 PT is a PermaTorque cylinder head gasket set engineered specifically for the real-world repair environment. Designed to deliver a reliable, long-lasting seal on even the most demanding applications, this head gasket set utilizes application-specific materials and proprietary sealing technologies to restore compression and prevent coolant or oil intrusion.

As one of the most critical components in any engine rebuild or head gasket replacement job, this set is built to withstand the constant stresses of thermal expansion, contraction, surface warping, and combustion pressure — sealing coolant and oil passages throughout the engine block and cylinder head interface.

Key Features:

• PermaTorque MLS with LaserWeld Technology — Multi-layer steel (MLS) construction with laser-welded stopper layer provides a precisely controlled compression limit for a stronger combustion seal
• No-Retorque Steel Core Design — Eliminates the need for retorquing head bolts after installation
• Proprietary NextGen Coating — Nonstick anti-friction coating accommodates surface finishes as rough as 80 Ra, sealing minor scratches and imperfections
• High-Temperature Resistance — Exclusive coatings withstand higher engine temperatures and compensate for imperfect sealing surfaces
• Directional Installation Markings — Most gaskets include orientation indicators to ensure correct installation when gasket direction is critical
• Complete Set — Includes all parts needed for the head gasket repair unless otherwise noted
• Graphite or Reinforced Fiber Facing — Steel armor construction for added strength and durability

Fel-Pro head gaskets are tested on-vehicle and validated to ensure optimal performance. Each gasket is application-engineered to match the correct surface finish requirements for a precise, leak-free seal. Prior to installation, inspect and resurface the cylinder head and engine block as needed per OEM specifications.
