What is a 5-position cam-style preload adjuster?

This adjuster lets you change how much the spring is compressed before you even start riding. By turning the cam, you can make the suspension firmer or softer to better suit your weight, riding style, or if you're carrying a passenger or luggage.

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

Progressive rate springs get stiffer the more they are compressed. This means they can offer a more comfortable ride over small bumps but provide better support and control when you hit larger ones or during hard braking.

Do these shocks come with everything needed for installation?

These shocks include the preload adjuster and springs. It's always a good idea to check your Triumph's service manual for any specific installation procedures or additional hardware that might be recommended.

Product Details

When you're looking to get your Triumph Bonneville riding smoother and handling better, upgrading the rear shocks is a solid move. These 12.5-inch 412 Series shocks from Progressive are built to give your Bonneville an improved suspension experience, whether you're cruising around town or heading out for a longer ride.

The 412 Series shocks feature a double-wall steel body for durability, and they're nitrogen-charged with multi-stage valving to ensure consistent damping. This means you get a smoother, more controlled ride over bumps and uneven surfaces. You can also easily tune the ride to your preference using the 5-position cam-style preload adjuster. Whether you're carrying extra gear or riding with a passenger, you can dial in the right amount of support.

This particular model comes in a bright chrome finish, which looks sharp on many Bonneville models. They use progressive rate springs, meaning the spring gets stiffer as it's compressed, offering a good balance of comfort when you're just cruising and support when you need it most.
