31-4009 PS, asymmetrical fork monotube cartridge kit. Lowered height

For riders looking to drop their front end, this Progressive Suspension monotube cartridge kit provides a 1-inch to 2-inch lowered ride height for 2018 to 2025 Softail models. It is designed for 49mm forks, excluding inverted models, and uses an asymmetrical layout to optimize performance. One leg contains a progressive rate spring with a threaded preload adjuster, while the other houses a nitrogen-charged monotube damper. Equipped with Frequency Sensing Technology (FST), this kit improves stability and resists bottoming out, even with the lower stance. It comes as a complete kit to replace your factory internals, providing a much-needed boost in handling and style. Sold as a kit.
