The Fel-Pro 1137 PermaTorqueMLS engine cylinder head gasket is engineered for demanding performance applications and professional repairs. Designed to provide a reliable seal even on imperfect sealing surfaces, this gasket features proprietary materials that ensure durability and consistent performance under high cylinder pressures. Its construction is ideal for engines experiencing significant movement or scrubbing, such as those with dissimilar materials like aluminum heads on cast iron blocks. This gasket’s strategic sealing beads surround the combustion chamber and coolant passages, concentrating clamp load to prevent leaks and maintain engine integrity during intense operation.
The PermaTorqueMLS series represents the latest in Fel-Pro’s performance gasket technology, combining multi-layer steel (MLS) design for enhanced strength and sealing capability. This gasket is particularly suitable for engines used in racing, NASCAR SVO, or other high-stress environments where maintaining a perfect seal is critical. Designed with installer convenience in mind, it simplifies installation, helps resolve OEM design issues, and extends the longevity of engine components. Please note that this gasket is not intended for use in emission-controlled vehicles, ensuring it is optimized for performance rather than emissions compliance.
Constructed for ease of use and reliability, the Fel-Pro 1137 gasket supports demanding automotive repairs and high-performance engine builds. Its innovative design helps prevent coolant and combustion leaks, reducing the need for frequent maintenance or repairs. Whether for engine rebuilds, race applications, or high-performance modifications, this gasket provides a dependable sealing solution that meets the rigorous demands of modern automotive engineering.
