No, the lowering hardware is entirely optional. The high-performance springs and Gold Valve Cartridge Emulators will significantly improve your V-twin's handling and comfort at the stock ride height without any lowering.
Will this kit change my bike's handling at stock height?
Absolutely. Even without using the lowering hardware, the Gold Valve Cartridge Emulators and performance springs are designed to provide superior damping and spring rate, resulting in a more controlled, comfortable, and responsive front end compared to factory components.
Is this kit a direct bolt-on replacement?
Installation involves disassembling your front forks to replace the internal components. While many experienced home mechanics can tackle this, professional installation is recommended to ensure proper setup and safety.
