Each Bilstein OE replacement air spring is designed to connect directly into the original connectors on your vehicle, ensuring modification-free installation and restoration of the original feel of the vehicle.

Features include:
• OEM-quality standards
• Proven Bilstein gas pressure technology on springs with integral shocks/struts
• Responds to street and vehicle conditions in milliseconds for instant adaptivity
• Provides excellent comfort and perfect driving characteristics
• Axial bellows provide sensitive spring behavior with a comparably low rolling radius--ensures optimum functionality even in confined working chambers
