The Harddrive Scepter 25 +2" Heavy Weight Cartridge Kit is engineered to provide robust front suspension performance for Dyna models. Featuring a 25mm CNC damping piston and a nitrogen-charged IFP design, these cartridges ensure stable and consistent damping. With 15mm preload adjustability on both sides and 24-click compression and rebound adjusters, you can dial in your front end for optimal handling. While designed to perform exceptionally well out of the box, these extended +2" cartridges require two-inch longer fork tubes for proper installation.
