KYB Gas-a-Just Rear Shock for BMW X5

The KYB Gas-a-Just 555610 is an OE-style monotube shock absorber for the rear of the 2000-2006 BMW X5. It is built to restore original handling response while supporting vehicles that tow, carry added load, or run larger wheels and tires.

Key Features

  • Monotube OE replacement designed to restore factory control and handling
  • High-pressure gas and oil separation for consistent damping and quick response
  • Built for BMW X5 rear suspension use on work, tow, and heavier-tire applications
  • Triple chrome plated piston rod helps reduce seal wear from fluid leakage
  • Internal rebound spring and R-stop design support controlled suspension movement
  • Helps maintain the suspension performance that electronic safety systems rely on

Product Details

KYB Gas-a-Just shocks use a monotube design with separate working chambers: an air-free hydraulic section for control and a high-pressure nitrogen gas section for immediate response. That layout helps the shock react quickly to steering and road inputs while maintaining a comfortable ride in normal driving. For BMW X5 rear suspension service, KYB 555610 provides a direct-fit replacement approach focused on restoring the vehicle’s original ride characteristics.

This part cross-references Monroe Shocks & Struts 39051 for the same application.

Common Problems This Shock Can Address

  • Excessive rear bounce after bumps
  • Reduced steering response and body control
  • Rear-end instability when towing or carrying load
  • Uneven damping from worn or leaking shock absorbers
  • Suspension performance loss with heavier wheels and tires

Installation Notes

Compatible With 2000-2006 BMW X5, rear. Verify compressed length 14.76 in., extended length 18.77 in., stroke length 4.01 in., upper mount type S1 (12MM), and lower mount type E2 (15.2 x 66.3) before installation. KYB recommends pairing new strut mounts, part number SM5253, to reduce noise and vibration, and using strut boot SB107 to help protect the shock from dirt, debris, and salt. This part number is 555610.
