About This Product
This Progressive Suspension FST fork monotube cartridge kit is designed to elevate the performance of 2017 to 2025 Harley-Davidson Touring models. By adding 2 inches to the stock fork length, it provides a taller profile and improved handling characteristics. The kit utilizes asymmetrical gas-charged dampers with Frequency Sensing Technology to automatically adjust to road conditions, providing a smooth ride while resisting brake dive and bottoming out. It is a complete internal replacement that fits a wide range of models including the Road King, Street Glide, and Road Glide, though it excludes CVO models with inverted forks. This setup is pre-set for spring rate and damping, ensuring a high-performance feel right out of the box without needing fork modifications.
Manufacturer part number: 31-4011.
