What makes these shocks 'progressive'?

The springs are progressive rate, meaning they get stiffer as they are compressed. This allows for a more comfortable ride over small bumps and better control during hard braking or acceleration.

Do these shocks come with everything needed for installation?

These shocks include the springs and the preload adjustment mechanism. It's always a good idea to check your motorcycle's service manual for any specific installation hardware or tools required for your model.

Can I adjust the ride height with these shocks?

The 5-position cam-style adjuster primarily changes the spring preload, which affects how the suspension handles weight and responds to bumps. It does not change the overall length or ride height of the shock itself.

Product Details

Progressive is known for making well-built suspension components that offer a noticeable improvement for riders. These 412 Series shocks are a prime example, designed to give your cruiser a smoother, more controlled ride. They fit a wide range of popular motorcycles, including models like the Honda Valkyrie, Kawasaki Vulcan 1500, and Triumph Bonneville, making them a solid option for many riders looking to upgrade their stock suspension.

The construction here is solid, featuring a doublewall steel body that's built to last. Inside, they use nitrogen-charged, multi-stage valving that responds to speed changes, ensuring consistent damping whether you're cruising or hitting some bumps. You can also fine-tune your ride using the 5-position cam-style preload adjuster, letting you dial in the right feel whether you're riding solo or carrying a passenger.

These shocks come with progressive rate springs in a bright chrome finish, and you can also get optional full show chrome covers for an even more striking look. They're a popular choice because they offer a great balance of performance, adjustability, and value for your motorcycle.
