Mercedes-Benz C-Class Coilover Suspension Kit - KW - KW H.A.S. - `15-`21. A height-adjustable spring kit engineered for W205 C-Class models (2015–2021) that lets you dial ride height after installation while maintaining factory suspension functions.

The KW H.A.S. kit replaces fixed lowering springs with vehicle-specific, chrome-silicon steel springs and KW height adjusters so you can fine-tune each corner within a tested range. Designed to pair with factory adaptive or conventional dampers, the kit preserves driver assistance systems and comfort features while improving handling response and lowering the vehicle for a more purposeful stance. Included components such as elastomer bump stops and dust protection help guard the OEM damping components from road debris and wear.

Features

• Height-adjustable per corner with KW height adjuster for millimeter-precise lowering
• Vehicle-specific spring rates matched to factory dampers (electronic or standard)
• High-strength chrome-silicon steel springs with protective coatings
• Included bump stops and dust protection elements where applicable
• Developed and tested by KW engineering to work with W205 Mercedes-Benz systems
