Product Details

Bilstein B4 OE Replacement dampers are built for drivers who want to return their vehicle to original suspension behavior without changing the factory character. This rear shock absorber uses a twintube design and OE-style mounting points to support controlled ride quality, stable handling, and predictable damping on BMW 325xi and BMW 330xi applications. The 19-220598 shock absorber is a practical choice when the goal is to replace worn rear dampers with a component that follows original equipment standards.

The B4 OE Replacement line focuses on maintaining the vehicle’s original balance and response. For BMW 325xi rear shock absorber replacement or BMW 330xi rear suspension service, this part number 19-220598 provides a direct-fit solution that aligns with factory specifications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Excessive rear bounce after bumps or dips
• Reduced ride control from worn factory shocks
• Unstable rear-end behavior during cornering
• Uneven damping response over rough pavement
• Loss of original BMW ride feel on 325xi and 330xi models

Installation Notes and Tips

Verify rear-position fitment before installation. This shock absorber uses an upper stem mount and a lower eye 12mm mount, so confirm the mounting style matches the vehicle’s original hardware and suspension layout. Inspect related rear suspension components, including mounts and bushings, before replacing the shock absorber. Professional installation is recommended for proper torque and alignment of the rear suspension assembly.
