About This Product
Progressive Suspension adjustable monotube fork cartridge kit. It drops the front end one inch on 49 mm conventional forks. Fits 2018 to 2025 Softail models: Deluxe, Heritage, Slim, Street Bob, Breakout, Low Rider, and Fat Boy. The asymmetrical design runs a nitrogen-filled sealed deflective disc damper in one leg and a heavy-duty spring with externally adjustable preload in the other. This stops oil foaming and cuts fork flex. Road holding improves over a standard spring upgrade.
Manufacturer part number: 31-2542.
