Do I need to buy anything else to install this shock absorber?

This shock absorber is sold individually. While it's designed as a direct replacement for the rear, it's recommended to check if your lowering springs came with new hardware or if any original components need to be reused. Always refer to the manufacturer's installation instructions for a complete list of requirements.

Will this shock absorber work with stock height springs?

The Bilstein B8 Performance Plus shock absorber is specifically designed to be paired with lowering springs. Using it with stock height springs may not provide optimal performance and could potentially lead to premature wear due to the difference in travel and valving.

What is the main benefit of the monotube design?

The monotube design allows for a larger volume of oil and a more consistent damping force compared to traditional twin-tube shocks. This leads to better heat dissipation and more precise control, especially during spirited driving or when using stiffer lowering springs.
