49MM PROGRESSIVE HEAVY DUTY FORK SPRING KIT FOR HARLEY-DAVIDSON DYNA AND VROD

Enhance your front fork's performance with the Progressive Suspension Heavy Duty 49mm Fork Spring Kit. Designed to handle heavier loads without sacrificing comfort, these springs offer a progressive rate that dynamically adapts to the terrain: smooth on small bumps and firm on larger impacts.

Made with high-quality chrome-silicon wire and precision wound, they provide strength, durability, and a much more controlled feel than stock springs. Ideal for loaded bikes, heavier riders, or more aggressive riding styles.

The kit includes the necessary progressive springs and spacers for installation.
