If you're working on a 2015–2020 XG Street model, you know that standard Big Twin hardware doesn't always cross over. This Colony brake rotor screw kit is purpose-built for the XG500, XG750, and XG750A, providing the exact fasteners needed to secure your rotors. While the fitment covers a broad range of Dyna, FXR, Softail, Sportster, and Touring applications in general hardware terms, this specific kit is the go-to for the Street series. Using fresh, high-quality hardware during a rotor swap is the best way to prevent backing out or stripped heads down the road. It’s a small investment for the peace of mind that your stopping power is properly bolted down.
