Product Description

The Cometic C15732-071 DST Head Gasket is designed for high-performance Dodge Hellcat 6.2L Gen 3 HEMI engines and serves as the right-hand cylinder head sealing solution. Built with Cometic's Dual Stopper Technology (DST), it provides enhanced combustion sealing stability under extreme boost and high cylinder pressures, making it ideal for heavily modified or forced-induction builds.

Its 7-layer multi-layer steel construction and 0.071-inch compressed thickness allow precise control of compression ratio while maintaining exceptional sealing integrity. The integrated stopper design distributes clamping force evenly across the combustion surface, reducing bore distortion and improving gasket longevity under sustained high-load operation.

This gasket is intended for properly machined performance engines and delivers a direct-fit upgrade over standard OEM sealing components. It eliminates the need for additional machining or O-ring modifications while providing race-level durability for serious performance applications.
