What makes the progressive rate spring beneficial?

A progressive rate spring starts softer, absorbing smaller bumps and road imperfections more comfortably. As the suspension compresses further, the spring rate increases, providing more support and control during harder impacts or aggressive riding.

How do I adjust the preload on these shocks?

The preload on these Progressive shocks can be adjusted by hand. You simply thread the spring perch up or down to change the initial tension on the spring, which affects ride height and how the suspension initially reacts.

What is the warranty on these shocks?

Progressive Suspension offers a lifetime limited warranty on these 494 Series shocks. This covers defects in materials and workmanship for as long as you own the product.

About this part

Product Details

If you're looking to get more out of your 2006-2017 Harley Dyna's suspension, these 494 Series Heavy Duty Shocks from Progressive are a solid option. They're built with a focus on sport performance, offering a significant upgrade over stock for a wide range of riding conditions. Whether you're just cruising around town or pushing your bike on a track day, these shocks are designed to keep your ride controlled and comfortable.

At their core, these shocks use a high-pressure monotube design with deflective disc damping. This setup helps ensure consistent damping performance, meaning the shock reacts predictably no matter how hard you're riding. You can fine-tune the feel of your ride with adjustable rebound damping and by hand-threading the preload adjustment. The progressive rate spring also plays a key role, offering a softer initial feel that stiffens up as needed, providing a good balance between comfort and support. For those moments when the suspension compresses fully, an engineered jounce bumper with a built-in metal cup helps manage bottoming out smoothly.

These shocks are hand-built and individually tuned and dyno-tested by Progressive, so you know they've been checked for consistent performance. The lightweight aluminum body helps with heat dissipation, and they come with standard bushings for a direct fit. Progressive backs these shocks with a lifetime limited warranty, giving you added peace of mind.
