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

The 5-position cam-style preload adjuster lets you easily customize your suspension's firmness. You can dial it in to better suit your weight and riding style, ensuring a more comfortable and controlled ride.

What makes the damping 'multi-stage velocity sensitive'?

This means the shock absorber's valving adjusts its damping force based on how quickly the suspension is moving. It provides a smoother, more controlled response across different road conditions and speeds.

Do these shocks come with everything needed for installation?

These shocks are designed as a direct replacement. While they include the shocks themselves, it's always a good idea to refer to the manufacturer's installation instructions for any additional hardware or specific procedures.

These 412 Series shocks are a prime example, offering a great balance of performance and value for a wide range of Harley-Davidson motorcycles. If you're looking to dial in your ride comfort and handling, these 12.5-inch black shocks are a solid option.

Built with a durable doublewall steel body, these shocks feature nitrogen-charged, multi-stage valving that works to provide smooth and consistent damping.

The five-position cam-style preload adjuster is a key feature here, allowing you to easily fine-tune the suspension to match your riding style and load, from a lighter rider to a heavier one. They come equipped with progressive rate springs in a black finish, designed to offer improved performance across the entire suspension stroke.

These shocks fit a variety of Harley-Davidson models, including popular bikes like the Road King, Street Glide, and Electra Glide. They are designed to be a direct replacement, making installation straightforward for many riders. If you're looking to improve your motorcycle's suspension without breaking the bank, the Progressive 412 Series shocks are a popular choice.
