About This Product
If you have lost or damaged the adjuster on your rear suspension, this MCS pre-load adjustable shock absorber knob is the perfect fix. It is a direct replacement for OEM part number 54000137 and allows you to easily dial in your ride height and stiffness for different loads. This knob fits a wide range of 2018 to 2024 Softail models, including the Deluxe, Fat Boy, Sport Glide, Breakout, FXDRS, and Fat Bob, though it excludes models with cam-adjustable shocks like the Slim or Street Bob. It also fits 2023 to 2025 CVO Road Glide and 2025 Ultra models. Being able to adjust your pre-load on the fly is essential for maintaining comfort and handling when carrying a passenger or luggage.
Manufacturer part number: 573334.
