SB Mopar Head Gasket GASKET BORE 4.180in

The SB Mopar Head Gasket GASKET BORE 4.180in from FEL-PRO is a precision-engineered cylinder head gasket designed for small block Mopar engines requiring reliable sealing under high compression and heat. This gasket serves as the critical barrier between the cylinder head and engine block, preventing coolant and oil leakage while maintaining compression integrity. Engine builders, mechanics, and performance enthusiasts rely on quality head gaskets to ensure long-term engine durability and prevent costly internal damage.

Constructed with a steel core laminate design, the SB Mopar head gasket features a 0.039 inch compression thickness that provides the exact specification needed for proper cylinder head seating and combustion chamber volume. The 4.180 inch bore diameter is precision-matched to small block Mopar specifications, ensuring perfect fitment and seal capability across all cylinder ports. FEL-PRO's laminated steel core construction combines elastomer facings with reinforced steel layers, delivering superior durability against thermal cycling, pressure spikes, and the chemical attack from modern coolants and combustion byproducts.

This gasket is essential for anyone rebuilding, restoring, or servicing small block Mopar engines, including applications in classic vehicles and performance builds. Proper installation requires clean, smooth mating surfaces and torque specifications appropriate to your engine block material. Whether you're completing a full engine overhaul or replacing a failed gasket, the SB Mopar head gasket with 4.180 inch bore ensures OEM-quality sealing performance that protects your investment for years of reliable operation.
