What is a progressive rate spring?

A progressive rate spring changes its stiffness as it's compressed. It starts softer to absorb small bumps and becomes firmer under heavier loads, like during braking or hitting larger obstacles. This provides a balance of comfort and control.

Do these springs come with everything needed for installation?

The fork springs themselves are included. You may need to reuse some original fork components or acquire specific tools depending on your motorcycle's model and year. Refer to your service manual for detailed installation procedures.

What is covered by the lifetime manufacturer's warranty?

The lifetime manufacturer's warranty typically covers defects in materials and workmanship for as long as you own the motorcycle. It's always best to check the specific warranty documentation from Progressive Suspension for full details.

Product Details

These Progressive Rate fork springs are precision wound to offer a noticeable improvement in your ride. They're designed to soak up the small road imperfections that can jar your ride, but they're also firm enough to handle the bigger impacts without bottoming out. This updated spring rate also helps reduce the front end's tendency to dive when you apply the brakes, giving you more confidence during deceleration.

Built with a progressive rate, these springs adjust their stiffness based on how much they're compressed. This means you get a softer feel over small bumps and a firmer response when you need it most, like during hard braking or cornering. They fit a wide range of Harley-Davidson models, including popular bikes like the Road King, Electra Glide, and Heritage Softail, offering a more comfortable and controlled ride across many applications.

Progressive Suspension backs these springs with a lifetime manufacturer's warranty, so you can install them with confidence. They are designed to fit right into your existing fork tubes, making for a straightforward installation for many riders.
