Progressive Suspension Monotube Cartridge Kit for Fork (manufacturer part number: 31-4006) — a road/touring-oriented solution for those looking to firm up the front end without undertaking a complete fork redesign. This kit replaces the internal hydraulic components with high-performance gas monotube cartridges and incorporates custom fork springs, designed for more consistent handling on the road and during long rides.

• Type: Monotube cartridge kit (complete unit)
• Fork tube diameter: 49.00 mm (1.93")
• Height adjustment: Standard (lowering kits available up to -2" but not compatible with Low models)
• Origin: Made in the USA
• Objectives: reduce dive under braking, improve front end stability, enhance cornering grip, and limit bottoming out
• Installation: installs without major modifications to the fork

Designed for large touring bikes and CVO Harley-Davidson models (e.g. Road Glide ST/CVO and Street Glide CVO listed), this kit is aimed at riders who want more linear damping and increased control of front-end behaviour. Professional installation is recommended to maintain the tuning and safety of the fork.
