What is preload adjustment and why is it important?

Preload adjustment changes the initial tension on the shock springs. Adjusting it allows you to compensate for rider weight and cargo, ensuring the suspension works correctly and maintains proper ride height for better handling and comfort.

What kind of springs do these shocks use?

These shocks come with progressive rate springs. Progressive springs offer a softer initial response for comfort and then get stiffer as they compress, providing better support during hard braking or cornering.

Are these shocks filled with gas?

Yes, these shocks are high-pressure gas charged. This helps prevent the oil inside from foaming under heavy use, which ensures consistent damping performance even during demanding rides.

Product Details

Progressive is known for making well-built suspension components that offer a noticeable improvement over stock. These 412 Series shocks are a prime example, designed specifically to give your 2012-2016 Harley-Davidson FLD Switchback a smoother, more controlled ride.

This lets you dial in the right amount of support, whether you're riding solo or carrying a passenger and luggage.

With their black finish and progressive rate springs, these shocks not only perform better but also give your FLD Switchback a clean, custom look. They’re a solid option for improving your ride quality and handling.
