S&S Cycle 84-99 BT 96in Sidewinder Big Bore Stroker Kit - Wrinkle Black

If you're looking to significantly increase the displacement of your 80 cubic inch Harley-Davidson Evolution Big Twin engine, this S&S Cycle Sidewinder Big Bore Stroker Kit is a well-built and economical way to get there. This kit is designed to take your engine from its stock 80 cubic inches all the way up to a powerful 96 cubic inches, giving you a noticeable boost in performance and torque. It includes almost everything you need to complete the transformation, making it a comprehensive solution for your engine build.

At the heart of this kit is the S&S flywheel assembly, featuring a 4-5/8 inch stroke and a small diameter design that is dynamically balanced for smoother operation. This is paired with S&S 3-5/8 inch bore high tensile cast iron Sidewinder cylinders. It's important to note that to install this kit, your stock engine cases will need to be bored out to match the 3-5/8 inch cylinder bore. This process ensures a precise fit and allows for the larger displacement. The wrinkle black finish on the cylinders adds a clean, custom look to your engine build.

This kit is a substantial upgrade for your Big Twin engine. While it contains most of what you need, always refer to the manufacturer's installation instructions for a complete list of recommended tools and any additional components that might be necessary for your specific application. Please be aware that this kit is not CARB approved and cannot be shipped to California.
