Key Features

• OE-style replacement for Asian SUVs and crossovers
• Restores the designed control and handling of the Nissan Murano
• Nitrogen gas-charged, twin-tube construction
• Triple-lip fluid seal helps reduce oil and gas leakage
• Vehicle-specific, hand-assembled damping valves manage tire contact, steering response, and body movement
• Strong strut body and bracket design helps minimize flex and maintain alignment
• Electronic safety systems rely on suspension performance that matches factory intent

Product Details

The KYB Excel-G line is focused on returning the suspension to original operating characteristics rather than altering ride feel. Part number 344439 is made on KYB OE assembly lines using OE-quality components and is calibrated for factory-style damping on the rear of the Nissan Murano. This part cross-references Monroe Shocks & Struts (e.g., 37282) for the same application.

Fits 2003-2007 Nissan Murano, rear. The listed dimensions are 11.37 inches compressed length, 15.35 inches extended length, and 3.98 inches stroke length. Mounting details are lower mount type E2 (12.4 x 45) and upper mount type S1 (12 mm).

Common Problems This Part Addresses

• Excessive bouncing after bumps or dips
• Reduced rear-end stability during lane changes
• Longer stopping distances caused by worn suspension damping
• Uneven tire contact and inconsistent handling response
• Noise, vibration, or looseness from a worn rear shock absorber

Installation Notes and Tips

Fits 2003-2007 Nissan Murano, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends new strut mounts, part number SM5462, to reduce noise and vibration, and a KYB strut boot, part number SB103, to help protect the new unit from dirt, debris, and salt.

Quality Assurance

KYB is a major OE supplier, and the Excel-G line is built on the same assembly lines used for original equipment production. The design uses OE-quality components and factory-style calibration to help restore the vehicle’s original suspension performance.
