This premium gasket features a multi-layer steel (MLS) construction with stainless steel layers that provide superior sealing performance and durability under high compression and extreme temperatures.

Key Features:

• 3.875-inch bore diameter for precise fitment on big bore Twin Cam applications
• .051-inch compressed thickness for optimal compression ratio tuning
• Multi-layer stainless steel (MLS) construction for maximum strength and heat resistance
• Advanced embossment technology ensures consistent clamp load and sealing pressure
• High-temperature coatings prevent corrosion and improve sealing surface
