What is the main benefit of the monotube design in these shocks?

The 46mm monotube design helps prevent performance fade, meaning the shock absorber will maintain consistent damping performance even during extended use or under demanding conditions.

How does the digressive valving work?

The patented digressive valving is velocity-sensitive, meaning it reacts instantly to changes in road conditions. This allows the shock to adjust its damping force quickly for improved handling and a more comfortable ride.

Does this shock absorber come with any mounting hardware?

This product listing is for the shock absorber only. It is designed as a direct fit, but it's always a good idea to check the manufacturer's installation instructions or consult with a professional to confirm if any additional hardware is needed for your specific vehicle.
