Progressive Monotube Fork Cartridge Kit For Harley Touring 2017-2025
Essential Performance: Progressive Monotube Fork Cartridge Kit for Harley Touring (2017–2025)
The Progressive Suspension Monotube Fork Cartridge Kit is a critical handling and comfort upgrade designed for the latest generation of Harley-Davidson Milwaukee-Eight (M8) Touring models from 2017 through 2025. This advanced cartridge system replaces the stock dual-bending valve or basic internal components with a premium, self-contained monotube design, delivering vastly superior, consistent damping control that transforms the stability, cornering, and ride quality of your Street Glide, Road Glide, or Electra Glide.
Monotube Technology: Consistency and Control
Progressive’s Monotube design is proven to deliver high-performance, consistent damping far superior to the stock components.
Superior Damping Control: The Monotube Cartridge Design provides highly controlled, non-fading damping across the entire stroke. This eliminates the often harsh and sometimes uncontrolled feel of the factory suspension, especially when riding aggressively or hitting sharp bumps.
Eliminates Brake Dive: A primary benefit is the significant reduction in front-end dive under braking. The controlled hydraulic damping of the Progressive Suspension M8 Fork Kit maintains a level chassis, improving stability and rider confidence.
Smoother Ride Quality: The system excels at managing energy from road imperfections, offering a much more compliant and comfortable ride over rough roads while retaining excellent support.
Linear Rate Springs: The kit includes specially designed linear-rate springs that work seamlessly with the monotube damping, providing predictable support throughout the full travel range.
Features for the Modern Touring Platform
This Harley Touring Front Suspension Upgrade 2017-2025 is designed for the modern M8 chassis, ensuring a straightforward and impactful upgrade.
Direct Bolt-In Installation: The kit is engineered for a direct, bolt-in replacement of the factory internals in the 49mm forks of all 2017-2025 Harley Touring models (FLH/FLT variants).
Simplified Service: The design of the cartridge system simplifies future fork maintenance compared to complicated, multi-component stock systems.
Enhanced Handling: By stabilizing the front end, the kit provides sharper steering response, better tire contact, and improved overall handling precision for the heavy touring bikes.
The Progressive Monotube Cartridge Kit M8 Touring is the best value and most effective way to eliminate the limitations of the stock suspension and achieve a truly stable, comfortable, and controlled ride on your late-model Harley Touring motorcycle.

Fitment Notes & Exceptions
Changing ride height can potentially change many carefully-engineered attributes of your bike, including trail
A change in ride height at one end of the vehicle usually will require a change at the other end
Prior to purchasing front-end components that are different than your OEM length, please verify that wheel and suspension travel can be altered without causing clearance issues – common interference spots include triple trees, fenders, frame, and of course, the ground
