What is included with the Progressive 412 Series Shocks?

This product includes a pair of 13.0-inch chrome shocks with progressive rate springs already installed. The shocks feature a doublewall steel body and a five-position cam-style preload adjuster.

How do I adjust the preload on these shocks?

The shocks have a five-position cam-style preload adjuster. You can rotate the cam to select the desired preload setting, which helps you tune the suspension for your weight and riding conditions.

What is the benefit of progressive rate springs?

Progressive rate springs offer a more comfortable initial ride by being softer at the beginning of their compression. As the spring is compressed further, the rate increases, providing more support and preventing bottoming out during harder impacts or when carrying extra weight.

About this part

Product Details

When you're looking to improve your motorcycle's ride, the Progressive 412 Series shocks are a solid option that offers a lot of value. These shocks are built with a doublewall steel body, which is a strong construction that can handle the demands of the road. Inside, they feature nitrogen-charged, multi-stage valving that works to provide smooth and consistent damping, helping to absorb bumps and keep your ride stable.

What's included with this specific set are the 13.0-inch chrome shocks. They come with progressive rate springs, which means the spring rate changes as it's compressed, offering a softer initial feel and firmer support as needed. You also get a five-position cam-style preload adjuster. This lets you easily dial in the suspension to match your riding style or load, whether you're riding solo or carrying a passenger.

These shocks are designed to fit a range of Harley-Davidson Sportster models, offering a noticeable improvement over stock suspension. They are a well-built component that can make a real difference in how your bike handles and feels on your rides.
