How do I adjust the rebound on these Koni shocks?

The rebound adjustment is done internally. You'll typically use a tool to turn a knob or screw located at the top of the shock absorber. Refer to the Koni installation manual for the specific procedure for your 8040 series shocks.

Do these shocks come with new hardware or mounts?

This product listing is for the Koni Sport shock absorber itself. It's recommended to inspect your existing strut mounts and hardware during installation and replace them if they show signs of wear or damage.

What is the difference between these and factory shocks?

These Koni Sport shocks offer adjustable rebound damping, allowing for a firmer ride and improved handling compared to stock. They are designed to provide a more responsive feel for drivers who want enhanced performance.

Product Details

If you're looking to get a more connected feel from your 2015-2018 Mercedes-Benz C300, C400, or C63 AMG, these Koni Sport shocks are a solid option. They replace the factory front struts and offer a noticeable improvement in handling and steering response, especially when you're pushing the car a bit. These are the yellow ones, a well-known performance upgrade from Koni.

What makes these stand out is the internal rebound adjustment. You can actually dial in how the shock controls the extension stroke, which is key for controlling body roll and keeping the tires planted during spirited driving. They use a twin-tube, low-pressure gas design, which helps maintain consistent damping performance. They're built to be a direct replacement, so installation should be straightforward, though you'll want to refer to the manufacturer's instructions for the specific adjustment procedure.

These shocks are a great way to wake up the handling of your W205 chassis Mercedes without going to a full coilover setup. Just remember they are designed for models without the factory air suspension or all-wheel drive.
