Why riders pick this

The Harddrive Scepter 25 +2" Cartridge Kit is engineered by Racing Bros to provide a significant performance upgrade for Dyna models. Featuring 25mm CNC 7075-T6 damping pistons and a nitrogen-charged IFP design, these cartridges ensure stable and consistent damping. While pre-tuned to offer excellent ride quality out of the box, they also include full adjustability for preload, compression, and rebound, allowing you to fine-tune your suspension to perfection. Remember, the +2" cartridge length necessitates the use of two-inch longer fork tubes for proper installation.
