About Harddrive
Harddrive is the house performance and replacement line built for American V-twins, covering everything from engine hardware and electrical to controls, lighting and chassis parts. The range is aimed squarely at Harley-Davidson and Indian riders who want a direct-fit part without dealer pricing, and it spans decades of model years — from Evolution-era Softails to current Milwaukee-Eight baggers.
Elevate your 2006-2017 Harley Dyna's front suspension with the Harddrive Scepter 25 +2" Medium Weight Cartridge Kit. This advanced system features 25mm CNC damping pistons and a nitrogen-charged IFP system for stable, responsive handling.
Why riders pick this
- Improved stability and feedback with +2" extended cartridges

- Nitrogen-charged IFP system for continuous dampening
- High-strength Cr-Si steel springs for consistent rate
- Fully adjustable preload, compression, and rebound
The Harddrive Scepter 25 +2" Medium Weight Cartridge Kit by Racing Bros is engineered to provide a significant performance boost for your Dyna. With 25mm CNC 7075-T6 damping pistons and a nitrogen-charged oil/gas separation system, these cartridges deliver stable damping with excellent feedback across a wide range of riding conditions. While pre-tuned for a supple ride right out of the box, full adjustability for preload, compression, and rebound allows you to dial in your perfect setup. It's crucial to note that these extended +2" cartridges require two-inch longer fork tubes for proper installation.
