Product Details

Monroe’s OESpectrum passenger car shock absorber line focuses on restoring original factory drivability while improving handling precision and control. For the Chevrolet Malibu, Pontiac G6, and Saturn Aura rear suspension, part number 5778 uses OE-style mounting dimensions and a metal dust shield to support consistent operation in everyday driving. This part cross-references KYB (e.g., 343454, 349008) for the same application.

Common Issues This Part Can Address

• Excessive rear-end bounce over bumps
• Loose or unsettled handling from worn shock absorbers

Installation Notes and Tips

Verify rear fitment by year, make, and model before ordering. This Monroe 5778 shock absorber uses a stem upper mount and loop bushing lower mount, so confirm the mounting style matches the vehicle’s original rear shock configuration. Inspect surrounding suspension components, bushings, and hardware condition during replacement to avoid repeat service.
