What is a progressive rate fork spring?

A progressive rate spring gets stiffer as it compresses. This design allows it to absorb small road imperfections for a comfortable ride, while also providing increased resistance for larger impacts or hard braking.

Will these springs make my ride feel too stiff?

The progressive rate is designed to balance comfort and control. They soak up small bumps for a smoother ride, but firm up during braking or when hitting larger imperfections to prevent excessive front-end dive.

What is covered by the lifetime manufacturer's warranty?

The lifetime manufacturer's warranty covers defects in materials and workmanship for the life of the product. It's a good indicator of the manufacturer's confidence in the product's durability.

Product Details

When you're out on your 2009-2013 Harley-Davidson FLHTCUTG Tri Glide Ultra Classic, the last thing you want is a jarring ride. These progressive rate fork springs from Progressive are designed to smooth out the road, soaking up those little bumps that can make a long ride uncomfortable. They're also tuned to be firm enough for the bigger impacts, giving you a more controlled feel.

What makes these springs different is their progressive rate. This means they get firmer as they compress, which helps reduce that front-end dive you often feel when braking hard. This improved control, combined with the comfort they add, makes a noticeable difference on the road. They are precision wound to ensure consistent performance.

This set is a direct fit for your Tri Glide Ultra Classic and also fits the 2010-2011 FLHXXX Street Glide Trike. They come with a lifetime manufacturer's warranty, so you can install them with confidence.
