About This Product
Progressive Suspension asymmetrical fork monotube cartridge kit for lowered ride height. It drops the front end 1 inch to 2 inches on 2018–2025 Softail models with 49mm forks, excluding inverted front ends. One leg gets a progressive rate spring with a threaded preload adjuster. The other leg gets a nitrogen-charged monotube damper. The asymmetrical layout with Frequency Sensing Technology resists bottoming out and improves stability. This replaces your factory internals. Sold as a kit.
Manufacturer part number: 31-4009.
Fitment
18-25 Softail (excl. inverted fork models)
