Tired of your front end diving under braking or feeling harsh over bumps, especially if you're a heavier rider? These Heavy-Duty Fork Springs from Progressive Suspension are the go-to upgrade for a substantial improvement in ride quality and control.

• Progressive Rate Advantage: These springs are soft enough at the start of their travel to soak up small road bumps for a "plush" ride, yet become firmer as they compress to absorb the big, molar-rattling ones.
  
• Heavy-Duty Performance: This version provides a firmer, high-performance feel, improves front-end stability, and is specifically designed to reduce front-end "dive" during braking, making it ideal for heavier riders or aggressive riding styles.
  
• Specific Fitment: Designed for 1999-2005 Harley-Davidson FXD, FXDC, and FXDL models, as well as 2004-2015 XL models.
  
• Complete Kit: This cost-effective upgrade includes the Progressive Suspension rate springs and the necessary preload spacers.
  
• Lifetime Warranty: Progressive Suspension stands behind their quality with a lifetime warranty on these fork springs.
