Cometic Chrysler B/RB 114.3mm Bore .040 inch MLX Cylinder Head Gasket

This is the Cometic Chrysler B/RB V8 MLX cylinder head gasket, designed for a 4.500 inch bore and .040 inch undersize. It's built to handle the demands of these classic Mopar V8 engines, ensuring a solid seal between your cylinder heads and engine block. If you're rebuilding or repairing the top end of your Chrysler, Dodge, or DeSoto with a B or RB engine, this gasket is a key component for a reliable seal.

Cometic uses their HP shim technology in this gasket, which helps increase the clamping force around the combustion chamber. This is especially beneficial for open deck blocks, as it creates a stronger seal where it matters most. The embossed outer layers are coated with Viton, a material known for its resistance to heat and oil, further enhancing the gasket's ability to maintain a seal under tough operating conditions. This well-built gasket is a popular choice for those looking to ensure their engine runs smoothly and reliably.
