What is the main purpose of these base gaskets?

These base gaskets create a seal between the engine cylinders and the crankcase. This is essential for preventing oil and compression leaks, ensuring your engine runs efficiently and cleanly.

What does '.020 Rubber Covered Steel' mean for the gasket?

This describes the gasket's construction. The steel core gives it strength and stability, while the rubber covering helps it conform to the engine surfaces for a better seal. The .020 inch thickness is a specific measurement important for engine assembly.

Are these gaskets sold individually or as a set?

These base gaskets are sold as a pair, meaning you receive two gaskets. This is convenient as most V-twin engines require two base gaskets, one for each cylinder.

Product Details

This is a Twin Power Base Gasket kit, designed for Harley-Davidson Evo Big Twin engines from 1984 to 1999. These gaskets are crucial for creating a solid seal between the cylinders and the crankcase, preventing leaks and ensuring proper engine compression. They replace Harley-Davidson part number 16774-86D.

Each gasket in this pair is constructed with a rubber-covered steel core. This design offers a good balance of sealing ability and durability, helping to maintain a tight seal even under the stresses of engine operation. The steel core provides rigidity, while the rubber covering conforms to mating surfaces for a more complete seal. The gaskets are .020 inches thick, which is important for maintaining correct cylinder deck height and valve timing if you're rebuilding or refreshing your top end.

This gasket set is designed to fit a wide range of Harley-Davidson models, including popular bikes like the Dyna Super Glide, Electra Glide Standard, and Heritage Softail. Sold as a pair, you'll have what you need to seal up both cylinders during engine work.
