Do your springs have you wound too tight? Progressive Suspension fork springs soak up small road bumps and have the ability to absorb the larger ones, too. Their progressively wound design provides you with the best of both worlds. When you install these fork springs, you'll be amazed at the improvement that you'll feel in the handling and ride of your machine. Straight rate springs can only offer linear resistance to compression and are a compromise. Give yourself the best ride and handling with Progressive Suspension fork springs. These springs are proudly made in the USA.
