Product Details

Part number 24-147644 is engineered for the rear of the Porsche 911 and is listed for standard suspension applications. The B4 OE Replacement line is focused on restoring original ride quality and handling feel, making it a practical choice when the factory shock has worn out and the vehicle needs predictable damping again. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Excessive rear-end bounce over bumps
• Reduced stability during braking and cornering
• Uneven or inconsistent damping from a worn shock
• Loss of original ride comfort in a Porsche 911
• Rear suspension noise caused by a fatigued damper

Installation Notes

Compatible With 1999-2005 Porsche 911, rear, standard suspension. Verify mount style before installation: stem upper mount and 12.2mm eye lower mount. Because this shock does not include a boot, reuse or replace the dust protection as needed during service. Confirm the vehicle’s suspension configuration and compare the original part number 24-147644 before installation.

Quality Assurance
