Twin Power 84-99 Evolution Big Twin Head Gasket 3.5 Inch Bore .040 MLS Pr

TwinPower is known for providing well-built parts for American V-Twins, and these head gaskets are no exception. If you're rebuilding the top end of your Evolution Big Twin engine from 1984 to 1999, these gaskets are designed to give you a solid seal. They feature a Multi-Layer Steel (MLS) construction, which is a popular choice for its ability to handle heat and pressure effectively, helping to prevent leaks where it matters most.

These gaskets are built for a 3.5-inch bore with a .040-inch thickness, making them suitable for a range of Evolution Big Twin applications. The MLS design uses multiple layers of stainless steel with a specialized coating to create a strong, flexible seal that conforms to the cylinder head and engine block surfaces. This updated construction helps ensure an airtight seal, crucial for maintaining compression and preventing oil or coolant leaks, especially in higher-performance builds.

This set includes two head gaskets, enough for one engine. They are made in the USA, reflecting a commitment to domestic manufacturing. When working on your Harley-Davidson, using well-made gaskets like these helps ensure the integrity of your engine rebuild.
