Product Details

The Bilstein 22-306623 B4 OE Replacement Suspension Strut Assembly is a direct-fit replacement strut designed to restore your vehicle's original ride quality and handling characteristics. Engineered to meet or exceed original equipment manufacturer (OEM) standards, this strut assembly delivers the precise damping performance your vehicle was designed with from the factory.

Bilstein's B4 OE Replacement line is built using the brand's renowned monotube gas pressure technology, which provides consistent, fade-free damping response under all driving conditions. Unlike twin-tube designs, the monotube construction separates the working gas and oil for superior heat dissipation and more responsive performance.

Key Features:

  • Direct OE replacement — no modifications required for installation
  • Meets or exceeds original equipment specifications and standards
  • Monotube gas pressure damper design for consistent, fade-free performance
  • Restores factory ride quality, handling, and vehicle control
  • Built to Bilstein's world-renowned quality and durability standards
  • Corrosion-resistant finish for long service life
  • Manufactured in ISO-certified facilities

The Bilstein B4 OE Replacement strut assembly is the ideal solution for drivers looking to restore their vehicle's original suspension performance without upgrading to a performance tune. It's a straightforward, confidence-inspiring replacement backed by Bilstein's decades of suspension engineering expertise.
