Engineered for consistent performance, the HARDDRIVE Scepter Spring utilizes a high-strength Japan Cr-Si steel material to deliver a stable spring rate and superior fatigue resistance. The system features a high-performance cartridge with an IFP design, incorporating a 25mm CNC 7075-T6 damping piston to ensure reliable damping quality. A nitrogen-charged oil/gas separation system maintains continuous dampening, while the adjustable cartridges offer 24 clicks of wide-range rebound and compression adjustment. Additionally, the setup provides 15mm of preload adjustability on both sides, allowing for precise tuning across multiple available spring rate options.
Selecting the appropriate spring weight is critical for optimal handling based on total rider and cargo load. The STD weight is recommended for combined weights up to 210lbs, while the MED weight supports loads from 211 to 280lbs. For heavier applications, the HVY weight is designed for combined weights of 281lbs and above. Note that +2" cartridges require 2" longer fork tubes for proper installation. This component is not compatible with 2016-2017 Lowrider S models.
