S&S Cycle 84-99 BT Super Stock Cylinder Head Kit For 3-1/2in and 3-5/8in Bore - Wrinkle Black

This S&S Cycle Super Stock Cylinder Head Kit gives you a pair of well-built heads designed for Harley-Davidson Big Twin engines with 3-1/2 inch and 3-5/8 inch bore sizes. These heads are a popular choice for riders looking to improve their engine's performance, offering a solid upgrade over stock components. The wrinkle black powder coat finish not only looks sharp but also adds a layer of durability to the cast aluminum construction.

When you open the box, you'll find the two cylinder heads, ready for installation. These aren't just replacements; they're designed to help your engine breathe better, potentially leading to improved power delivery and throttle response. The cast aluminum construction is chosen for its balance of strength and weight, making it a practical material for performance engine components. The wrinkle black finish is applied evenly, providing a consistent look that holds up well to engine bay heat and general wear.

This kit is a significant upgrade for your Big Twin, suitable for a wide range of Harley-Davidson models from 1984 through 1999, including popular bikes like the Softail Custom, Dyna Super Glide, and Electra Glide Classic. Because these are performance heads, it's always a good idea to consult the manufacturer's installation instructions to ensure proper setup and to see if any other supporting modifications or components are recommended for your specific build. This ensures you get the most out of the improved airflow these heads offer.
