OE Replacement Ride Control

Bilstein B4 OE Replacement shock absorber 19-304472 is engineered to restore original ride quality and handling while meeting or exceeding OE standards. It is a rear suspension shock absorber for vehicles without electronic suspension, with fitment for BMW Z4 and Toyota GR Supra applications.

Key Features

  • Twintube internal design for controlled damping response.
  • Black painted finish for corrosion-resistant appearance.
  • Eye lower mount and stem upper mount for direct-fit installation.
  • B4 OE Replacement series tuned to maintain factory ride characteristics.
  • Bilstein shock absorbers are built to OE-level standards.

Detailed Description

The Bilstein 19-304472 is part of the B4 OE Replacement line, a product series focused on restoring factory-style suspension performance without changing the vehicle’s original ride character. This rear shock absorber uses a twintube design, black paint finish, eye lower mount, and stem upper mount to match the intended application. It fits 2019-2026 BMW Z4, rear, without electronic suspension, and 2020-2026 Toyota GR Supra, rear, without electronic suspension. This part cross-references BMW and Toyota OE numbers (e.g., 33 52 6 879 207, 48530-WAA03) for the same application.

What It Helps Address

  • Excessive bouncing or reduced damping control.
  • Loss of original ride comfort and road feel.
  • Worn rear suspension response on BMW Z4 and Toyota GR Supra models.
  • Handling changes caused by aging OE shock absorbers.

Installation Notes

Verify rear fitment and confirm the vehicle is equipped without electronic suspension before ordering. Match the mount style and application details to the existing shock absorber. Professional installation and a post-installation alignment check are recommended whenever suspension components are replaced.

Quality Assurance

Bilstein B4 OE Replacement dampers are engineered to meet or exceed OE standards and are backed by Bilstein’s established suspension manufacturing experience.
