About This Product
The Progressive Suspension Monotube Fork Lowering Kit is designed for riders who want to improve handling while achieving a lower stance. This kit replaces the stock fork internals with a high-performance gas-charged monotube damper that is specifically valved for a lowered configuration. Unlike traditional lowering kits that can compromise ride quality, this monotube system maintains excellent damping control and prevents bottoming out. It is an ideal solution for custom Harley-Davidson projects where a sleek profile is desired without sacrificing comfort. This product is sold as a pair and includes all necessary components to lower the front end effectively.
Manufacturer part number: 31-2504.
