Product Details

PRT Performance Ride 373249 is a rear suspension shock absorber engineered around the listed Infiniti FX35 and FX45 rear applications. The gas-charged construction supports stable damping, while the measured compressed and extended lengths help match the original suspension geometry for the specified vehicles. The center-of-the-bolt upper measuring point and center-of-the-loop lower measuring point are important for proper application matching on the rear of the Infiniti FX35 and Infiniti FX45.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Addresses

• Rear suspension bounce after bumps or dips
• Excessive body movement over uneven pavement
• Reduced rear damping performance on Infiniti FX35 and FX45 models
• Noise or harshness from worn rear shock components
• Uneven rear ride control caused by aging shock absorbers

Installation Notes and Tips

Verify rear fitment by matching the vehicle year, model, and mounting style before installation. Confirm the compressed length, extended length, and mount types against the original unit on the Infiniti FX35 or FX45 to ensure correct replacement. Because this shock absorber uses a bolt upper mount and loop lower mount, alignment with the existing suspension points is essential for proper installation.

Quality Assurance

PRT Performance Ride 373249 is built as a suspension shock absorber for the specified rear Infiniti applications and follows the listed dimensional and mounting specifications for fitment accuracy.
