What is the main benefit of the 5-position preload adjuster?

The 5-position cam-style preload adjuster allows you to fine-tune the suspension's stiffness. This means you can adjust the ride to better suit your weight and riding conditions, whether you're riding solo or with a passenger and luggage.

What does 'progressive rate springs' mean for my ride?

Progressive rate springs offer a more adaptable ride. They start softer for initial comfort over small bumps and gradually stiffen as they compress under load, providing better support during hard braking or cornering.

Are these shocks filled with gas?

Yes, these shocks are high-pressure gas charged. This helps to prevent the oil from foaming under heavy use, ensuring consistent damping performance and a smoother ride.

About this part

Product Details

If you're looking to give your Harley-Davidson a more comfortable and controlled ride, these Progressive 412 Series shocks are a solid option. They're designed to be a direct replacement for your stock shocks, offering a significant improvement over the original equipment. The 13.5-inch length provides a classic look and feel, and the chrome finish adds a touch of style to your bike.

What makes these shocks work so well is their well-built construction. They feature a double-wall steel body that's built to last, housing a nitrogen-charged damping system. This system uses multi-stage, velocity-sensitive valving to ensure smooth and consistent damping, whether you're cruising on the highway or navigating rougher roads. Plus, the five-position cam-style preload adjuster lets you easily fine-tune the suspension to match your riding style and load, from a lighter rider to a heavier load.

With their durable build and adjustable damping, these 412 Series shocks are a popular choice for riders seeking a better suspension experience. They come with progressive rate springs in a bright chrome finish, and you can choose between standard or heavy-duty spring options depending on your needs.
