S&S Cycle 1999+ BT .030in 4-1/8in Head Gasket - 2 Pack

S&S Cycle is well-known for making performance engine parts for Harley-Davidson motorcycles. This set of two head gaskets is designed for 1999 and newer Big Twin models, featuring a stock bolt pattern and specifically accommodating Twin Cooled heads. They are built to a .030 inch oversize and a 4-1/8 inch bore, which is important if you've had machine work done on your cylinders or are using larger bore pistons.

These gaskets are constructed from layered steel, a durable material that helps ensure a solid seal between your cylinder head and the cylinder block. The layered steel design allows for some flexibility to conform to the mating surfaces while maintaining sealing integrity under the pressures and temperatures of an engine. Having two gaskets in the pack means you have what you need for both cylinders.
