S&S Cycle 99-06 BT 106in Stock Bore Stroker Kit w/ Sprocket Bearing

If you're looking to get more out of your Harley-Davidson Big Twin's engine, increasing its displacement is a solid way to achieve that. This S&S Cycle Stock Bore Stroker Kit is designed to help you achieve a 106 cubic inch displacement from your stock 88 cubic inch engine, offering a significant boost in power and torque. It's an economical approach to a bigger engine, especially when you consider the gains you can expect.

What makes this kit a smart choice is that it allows you to use your existing stock cylinders, which only need to be bored out to 37/8 inches to accept the included S&S pistons. Alternatively, you can opt for a pre-fit S&S cylinder and piston kit if you prefer. This stroker kit is designed to work with either your stock cylinder heads or S&S cylinder heads, giving you flexibility in your build. For fuel-injected models, remember that a recalibration of the fuel injection system will be necessary after installation to ensure optimal performance.

This kit includes the necessary components to increase your engine's displacement, including the sprocket bearing. It's a well-built package from S&S Cycle, a name known for performance engine components. While this kit is designed for a wide range of Harley-Davidson Big Twin models from 1999 to 2006, including popular bikes like the Road King, Fat Boy, and Street Glide, it's always a good idea to verify fitment for your specific motorcycle. Keep in mind that this kit is not CARB approved and cannot be shipped to California.
