What is the benefit of progressive rate springs?

Progressive rate springs get stiffer as they are compressed. This means they offer a softer initial feel for comfort over bumps but become firmer under load or hard cornering, providing better support and control when you need it.

How do I adjust the preload on these shocks?

These shocks have a five-position cam-style preload adjuster. You can rotate the cam to select the desired spring tension, which affects ride height and how the suspension responds to weight.

What is the advantage of gas-charged damping?

High-pressure gas charging helps prevent the damping fluid from foaming under heat and stress. This leads to more consistent and reliable damping performance, especially during spirited riding or when carrying extra weight.

Product Details

When you're looking to dial in the ride on your 2016-2019 Triumph Thruxton 1200, upgrading the rear shocks makes a big difference. The Progressive 412 Series shocks are built to give you a smoother, more controlled feel on the road. They replace your stock units with a well-built design that's made to last.

These shocks feature a double-wall steel body and are charged with high-pressure nitrogen gas. This setup helps ensure consistent damping performance, meaning you get a more predictable ride whether you're cruising or pushing it a bit. The springs are a progressive rate, which means they get stiffer as they compress, offering a good balance of comfort and support for different riding styles and loads. You can easily adjust the spring preload using the five-position cam-style adjuster to fine-tune the ride height and how the bike handles.

This particular set comes in a black finish with black springs, giving your Thruxton a clean, understated look. They are a direct fit for your bike, making the installation straightforward.
