KYB 349063 Shock Absorber - Rear

KYB Excel-G Rear Shock for Mazda 6

The KYB Excel-G 349063 is a rear suspension shock absorber for 2009-2013 Mazda 6 models. It is built to restore original ride control, stability, braking response, and handling without changing the vehicle’s factory-tuned behavior.

As part of the KYB Excel-G line, this shock is calibrated for OE-style performance and assembled using OE-quality components on KYB production lines. For Mazda 6 rear suspension service, 349063 is a direct replacement focused on restoring the way the vehicle was designed to respond.

Product Details

The KYB Excel-G 349063 is engineered as an OE-style replacement shock absorber for the rear suspension on the Mazda 6. It uses a twin-tube, nitrogen gas-charged design and internal valving tuned to restore factory ride control rather than alter it. With a compressed length of 14.21 inches, extended length of 21.27 inches, and 7.06 inches of stroke, this unit is built to match the application’s suspension geometry. Lower mount type is E2 (14.5x40) and upper mount type is E2 (12.2x40).

This part cross-references Monroe Shocks & Struts 5656 for the same application.

What It Helps Address

• Excessive rear-end bounce over bumps
• Loose or unsettled handling in the Mazda 6
• Reduced braking stability from worn rear shocks
• Delayed lane-change response and body movement
• Uneven tire contact caused by weak damping

Installation Notes

Install on 2009-2013 Mazda 6 rear applications only. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify mount orientation, suspension travel, and hardware condition before installation. Because this unit is application-specific, confirm part number 349063 against the vehicle’s rear suspension configuration before service.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers, and the Excel-G line is produced on KYB OE assembly lines using OE-quality components. The design focuses on restoring original suspension performance for the Mazda 6 while supporting proper operation of braking and electronic safety systems that depend on suspension control.
