HARDDRIVE R3050077 Scepter Option Spring HVY 39mm

The HARDDRIVE Scepter Option Spring HVY 39mm, part number R3050077, is designed for riders and cargo with a combined weight of 281 pounds and up. The cartridge system provides adjustable preload, compression, and rebound settings for tuning suspension performance.

This high-performance cartridge uses an IFP design with a 25mm CNC 7075-T6 damping piston to support stable damping quality. A nitrogen-charged oil/gas separation system helps provide continuous dampening, while the high-strength Japan Cr-Si steel spring is designed for a consistent spring rate and fatigue resistance.

Rebound and compression adjustments each offer 24 clicks, and preload is adjustable by 15mm on both sides. The +2-inch cartridge option requires 2-inch longer fork tubes. This product will not fit the 2016–2017 Lowrider S.
