The HARDDRIVE Scepter 25 Cartridge Kit delivers precise suspension tuning through a high-performance Internal Floating Piston (IFP) design. At the core of this system is a 25mm CNC-machined 7075-T6 damping piston, engineered to maintain stable damping quality under load. The assembly utilizes high-strength Japan Cr-Si steel springs, selected for their consistent spring rate and superior fatigue resistance. To ensure continuous dampening performance, the cartridge employs a nitrogen-charged oil/gas separation system, providing reliable operation across varied riding conditions.
Adjustability is maximized with 24-click wide-range rebound and compression adjusters, alongside 15mm of preload adjustability on both sides. Riders can select from multiple spring rate options, including STD, MED, and HVY weights, tailored to combined rider and cargo loads ranging from under 210lbs to 281lbs and above. Note that these +2" cartridges require 2" longer fork tubes for proper installation. This kit is not compatible with 2016-2017 Lowrider S models.
