The ULT-SL EXH GSKT 426 HEMI by Mr. Gasket is a precision-engineered exhaust gasket designed specifically for the legendary 426 Hemi engine platform. This gasket serves as a critical seal between the cylinder head and exhaust manifold, preventing combustion gases from escaping at the joint and ensuring optimal engine performance. Whether you're rebuilding a classic muscle car, restoring a vintage Mopar, or maintaining high-performance equipment, this exhaust gasket is an essential component for maintaining proper sealing integrity.
Mr. Gasket's Ultimate Seal (ULT-SL) gasket line represents advanced sealing technology that withstands the extreme temperatures and pressures generated by the 426 Hemi's combustion process. The gasket material is engineered to resist thermal cycling, preventing degradation and leakage that can develop over time with conventional gaskets. At just 0.28 lbs and measuring 23 inches in length, this gasket fits the specific dimensional requirements of the 426 Hemi exhaust port configuration, ensuring proper alignment with manifold bolt holes and exhaust ports without gaps or misalignment that could compromise the seal.
Mechanics and engine builders working with 426 Hemi applications—from street rods to collector vehicles—will appreciate the reliability of Mr. Gasket's OEM-quality construction. Installation requires careful cleaning of both the cylinder head and manifold surfaces to remove old gasket material and carbon buildup before positioning the new gasket. This attention to detail ensures a long-lasting and effective seal for high-performance applications.
