Product Details

The Monroe OESpectrum Monotube Shock Absorber line is built for vehicles that use a monotube shock configuration from the factory. On the BMW X3, part number 39107 is tuned to help maintain handling precision and road control while reducing unwanted harshness through the suspension. The rear shock design uses a stem-style upper mount and a loop bushing lower mount, making it a focused replacement for the specified application. Monroe 39107 is a practical choice when replacing worn rear shocks on a 2004-2011 BMW X3.

What This Shock Absorber Helps Address

• Excessive rear-end bounce over bumps and uneven pavement
• Reduced damping control from worn shock absorbers
• Noise and harshness coming through the rear suspension
• Unstable ride feel during braking, cornering, or lane changes
• Loss of consistent rear suspension response on the BMW X3

Installation Notes and Tips

Verify rear suspension fitment by year, make, model, and mounting style before installation. Confirm the stem upper mount and loop bushing lower mount match the original shock configuration on the vehicle. Inspect surrounding suspension components, including bushings and mounting points, so the new shock absorber can operate correctly after replacement.
