• Monotube design — single-tube construction separates gas and oil for consistent, reliable damping
• OE replacement fitment — direct bolt-on installation with no modifications required
• Zinc-coated body — corrosion-resistant finish for long-term durability in harsh conditions
• Velocity-sensitive damping — automatically adjusts to road conditions for optimal comfort and control
• Self-adjusting design — continuously adapts to varying loads and driving conditions
• Made in Germany — manufactured to Bilstein's exacting quality standards
