Description
Stock fork springs compress under braking and load, degrading handling and comfort—especially for heavier riders or aggressive riding styles. Progressive Suspension’s Heavy-Duty Fork Spring Kit restores front-end control with a stiffer spring rate that reduces brake dive, improves stability, and delivers the firm, responsive feel demanded by performance-focused riders. This bolt-on upgrade pairs rate-matched springs with preload spacers for a tuned suspension feel without expensive revalving.
