What makes the springs 'progressive rate'?

Progressive rate springs start out softer and become stiffer as they are compressed. This design helps provide a more comfortable ride over small bumps while still offering good support during harder impacts or when carrying a load.

How do I adjust the preload on these shocks?

These shocks feature a five-position cam-style preload adjuster. You can rotate the cam mechanism to select your desired preload setting, allowing you to fine-tune the suspension for your riding style and load.

What is the benefit of nitrogen charging in the shocks?

Nitrogen charging helps maintain consistent damping performance by preventing oil aeration and foaming, especially under demanding conditions. This leads to a smoother and more reliable ride.

Product Details

Progressive Suspension is known for making well-built suspension components that offer a noticeable improvement over stock. These 412 Series shocks are a prime example, designed to give your motorcycle a smoother, more consistent ride. They fit a range of Harley-Davidson models, including popular bikes like the Sportster XLH1200 and FXRT Sport Glide, giving you a solid upgrade for your ride.

What makes these shocks a great value is their simple yet effective design. The doublewall steel body construction is strong and built to last, while the nitrogen-charged, velocity-sensitive valving ensures smooth damping across different speeds. You can easily fine-tune your ride using the five-position cam-style preload adjuster, letting you dial in the perfect setting whether you're carrying a passenger or riding solo. The bright chrome finish and chrome springs give your bike a classic look that stands out.

These shocks come with progressive rate springs, which means they start softer and get stiffer as they compress, offering a comfortable ride on the highway and better support when you need it. If you're looking to improve your motorcycle's handling and comfort, these 412 Series shocks are a well-made option.
