What is the spring rate on these shocks?

These shocks feature progressive rate springs. This means the spring rate changes as the suspension compresses, offering a softer initial feel that gets firmer under load for improved control.

Do these shocks come with mounting hardware?

This product listing is for the 412 Series shocks themselves. It is recommended to check the manufacturer's installation guide or contact them directly to confirm if any specific mounting hardware is included or if you need to reuse your original components.

Can I adjust the ride height with these shocks?

These shocks feature a 5-position cam-style preload adjuster, which allows you to adjust the spring tension. This affects how the suspension reacts to weight and bumps, but it does not change the overall physical length or ride height of the shock.

Product Details

You're getting a pair of Progressive 412 Series shocks, measuring 11.0 inches in length and finished in black. These shocks are built with a durable doublewall steel body and are nitrogen charged for consistent damping performance. They're designed to be a solid improvement over stock suspension, offering smoother control whether you're cruising or carrying a load. This set fits a wide range of Harley-Davidson motorcycles, including popular models like the Sportster 1200 Custom and FXRT Sport Glide.

The 412 Series shocks use a progressive rate spring, which means they start softer and get stiffer as they compress. This helps provide a comfortable ride over small bumps while still offering good support for larger impacts or heavier loads. You can easily tune the ride to your preference using the 5-position cam-style preload adjuster. This allows you to dial in the right amount of sag for your weight and riding style, ensuring a more balanced and controlled feel on the road.
