What makes these shocks an improvement over stock?

These shocks feature a nitrogen-charged, gas-filled design with multistage valving. This helps provide smoother, more consistent damping compared to many stock shocks, especially under varying road conditions.

How do I adjust the preload on these shocks?

The shocks have a 5-position cam-style preload adjuster. You can rotate this adjuster to change the spring tension, allowing you to fine-tune the ride stiffness based on your weight and riding style.

Are these shocks sold individually or as a pair?

These shocks are sold as a pair, providing matched performance for both sides of your motorcycle's rear suspension.

Product Details

If you're looking to improve your motorcycle's suspension performance, these Progressive 412 Series shocks are a solid option. They fit a wide range of bikes, including models like the Honda FT500 Ascot, Kawasaki KZ440 LTD, and Yamaha RD350. These shocks are built with a durable doublewall steel body and are nitrogen charged for consistent damping, making a noticeable difference in how your bike handles bumps and road imperfections.

The 412 Series shocks offer a well-built design that focuses on providing a smoother, more controlled ride. The multistage, velocity-sensitive valving works to adapt to varying road conditions, while the high-pressure gas charge helps prevent the oil from foaming, ensuring consistent damping performance. You can also fine-tune your ride using the 5-position cam-style preload adjuster, allowing you to set the suspension stiffness 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 opt for full show chrome covers on select applications for an even more striking look. They are designed to be a direct replacement for your stock shocks, making installation straightforward.
