S&S Cycle 1984+ BT Top Rocker Box - Die Cast Gloss Black

This is the S&S Cycle 1984 and later Big Twin Top Rocker Box, finished in a gloss black die-cast design. It's built to replace the stock rocker box on your Harley-Davidson Big Twin motorcycle, offering a clean, updated look while maintaining the performance you expect from S&S Cycle components. If you're looking to refresh the appearance of your engine or are undertaking a top-end rebuild, this piece is a solid choice for achieving a custom aesthetic.

Crafted from die-cast aluminum, this rocker box is both strong and relatively lightweight, which is important for engine components. The gloss black finish is applied evenly and is designed to hold up to the heat and vibration inherent in a motorcycle engine. This part is specifically designed to fit 1984 and newer Big Twin models, ensuring a direct fit without the need for modifications, provided your existing setup is standard. The precision of the casting means that mating surfaces will be flat and true, which is crucial for proper sealing and preventing oil leaks.

When installing, always ensure you have new gaskets on hand, as reusing old ones can lead to leaks. It's also a good time to inspect the rocker arms and pushrods for wear. This top rocker box is a key component in the overall look and function of your engine's top end, and the S&S Cycle name is well-known for producing reliable parts for Harley-Davidson motorcycles.
