Harley Davidson FXFB(S) Fat Bob 18-24 – lowering kit

Do you want better foothold and a lower seating position on your Harley Davidson FXFB(S) Fat Bob 18-24? Hyperpro's lowering spring kit gives you an effective lowering of 15 mm and at the same time a significant improvement in driving characteristics.

Lowering spring kit – the comfortable solution

This kit contains lowering springs for both the front fork and rear shock and is the most comfortable and technically advanced way to lower your motorcycle. Unlike simple lowering link kits, Hyperpro's spring kit maintains the original suspension balance while achieving a lower riding position.

Important things to know about lowering with a spring kit:
When lowering with a spring kit, the seat height does not change in an unloaded state, as the springs must have the same length as OEM in order not to sit loosely on the shock absorber. However, in a loaded state – when the rider is sitting on the motorcycle – the seat height will be the specified 15 mm lower. The progressively constructed Hyperpro spring thus provides both better comfort and an effective, controlled lowering while riding.

This system is superior in both comfort and stability because the springs work progressively throughout the entire stroke. You get a softer start to the suspension on small bumps, while the spring becomes harder on larger loads – providing optimal control without compromising comfort.

Advantages of Hyperpro lowering kit

• Lower center of gravity – improved stability and control in all driving situations
• Better foothold – safer stopping at low speeds and at traffic lights
• Progressive suspension – soft comfort on small bumps, firm control on heavy loads
• Harmonious balance – front and rear work together for optimal road contact
• Increased confidence – especially for shorter riders or those with shorter leg lengths

Assembly and setup

Professional installation is highly recommended. Correct preload, sag measurement and damping adjustment are essential to achieve the full effect of Hyperpro's progressive springs. A correct setup ensures that the motorcycle performs optimally in all riding situations.
