What is a progressive rate spring?

A progressive rate spring changes its stiffness as it compresses. This means it's softer on small bumps for comfort, but gets firmer under harder impacts or braking for better control.

What does 'Heavy Duty' mean for these fork springs?

The 'Heavy Duty' designation indicates these springs are stiffer than standard versions. They are intended for riders who may carry heavier loads, ride two-up frequently, or simply prefer a firmer front suspension feel.

Do these fork springs come with any kind of warranty?

Yes, these Progressive fork springs come with a lifetime manufacturer's warranty, offering peace of mind for your purchase.

Product Details

What you get in this kit are Progressive Rate Fork Springs, specifically the Heavy Duty version. These springs are designed to handle a variety of road conditions, soaking up small bumps for a more comfortable ride while still being firm enough to manage larger impacts. They're precision wound to offer a progressive rate, meaning they adapt to the force applied, providing a smoother experience over rough patches and a more controlled feel during braking.

The engineers at Progressive chose spring rates that help reduce the common front-end dive you experience when you apply the brakes. This not only contributes to a more comfortable ride but also helps maintain better stability. They fit a range of Harley-Davidson motorcycles, including models like the Dyna Super Glide, Sportster 1200 Custom, and Street 750, offering an improved feel for many riders.
