Bilstein 33-52-6-780-195 B4 OE Replacement Rear Shock Absorber

The Bilstein 33-52-6-780-195 is a B4 Series OE Replacement rear shock absorber engineered to restore factory ride quality and handling precision. Designed as a direct-fit replacement, this shock delivers the same performance characteristics as the original equipment it replaces, making it an ideal choice for drivers seeking a reliable, no-compromise suspension restore.

The Bilstein B4 line uses a gas-pressure design — available in both monotube and twin-tube configurations — that provides consistent damping performance over the life of the unit. Gas pressurization eliminates oil foaming under hard use, maintaining predictable handling and control in everyday driving conditions.

Key Features:

• B4 OE Replacement Series — engineered to match original factory suspension performance
• Gas-pressure damping technology — reduces aeration and maintains consistent response
• Rear axle application — twin-tube, gas-pressure design; absorber does not carry a spring
• Direct OE fitment — no modifications required for installation
• Zinc-coated body — provides corrosion resistance for long service life
• Bilstein part number: 19-145266
• OEM / Cross-reference part numbers: 33526780195, 33 52 6 780 195, 19-145266, 19145266

Bilstein has been a leading manufacturer of precision suspension components since developing the first monotube gas-pressure shock absorber for series production over 60 years ago. The B4 line reflects that heritage, offering broad passenger car coverage in both monotube and twin-tube versions.
