About this part

Product Details

If you're working on the transmission of your 1986-1999 Big Twin Harley-Davidson, whether it's a stock case or an S&S 4- to 5-speed conversion, this trap door kit is a solid upgrade. It replaces the stock trap door, offering a more robust and visually appealing component for your drivetrain.

This trap door is machined from high-strength billet aluminum, which means it's strong and lightweight. The material choice also allows for precise shaping, and this particular kit is polished to a show-quality finish, giving your transmission a cleaner, more custom look. It's designed to fit directly into stock transmission cases from 1986 through 1999, and it's also a perfect match for S&S Cycle's own 4- to 5-speed conversion transmission cases, making it versatile for various build types.

This kit is a great choice for riders looking to enhance the appearance and integrity of their transmission. It's a well-built part from a reputable brand known for performance motorcycle components.
