KYB Excel-G Rear Shock for Prius V

The KYB Excel-G 349218 is a rear suspension shock absorber for the 2012-2017 Toyota Prius V. It is built to restore original ride control, stability, braking response, and handling balance without changing the vehicle’s designed suspension behavior.

As part of the KYB Excel-G line, this shock is assembled on KYB OE production lines and uses OE-quality components calibrated for original performance. For Prius V owners looking for a rear shock replacement that matches factory tuning, part number 349218 is a direct OE-style choice.

Key Features

• Fits 2012-2017 Toyota Prius V, rear
• KYB Excel-G OEA replacement for original suspension performance
• Nitrogen gas-charged, twin-tube shock absorber design
• 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 construction helps minimize flex and maintain alignment
• R-stop design included

Product Details

The Excel-G line is engineered for drivers who want the suspension to perform as the manufacturer intended. On the Toyota Prius V, rear shock condition affects ride comfort, lane-change response, braking stability, and how consistently the tires stay planted on the road. KYB 349218 is calibrated to restore those characteristics using OE-style damping and construction.

This part cross-references Monroe Shocks & Struts 5502 for the same application. It also aligns with Toyota OE references 4853080595 and 4853080600 for rear shock replacement on the Prius V.

What It Helps Address

• Excessive rear bounce after bumps
• Reduced braking stability from worn rear shocks
• Loose or unsettled handling in lane changes
• Uneven tire contact caused by weak damping
• Suspension noise or poor ride control from worn shock absorber performance

Installation Notes

Compatible with 2012-2017 Toyota Prius V rear applications. Additional components may be required depending on the vehicle’s current suspension condition and service procedure. Verify compressed length, extended length, stroke, and mount type before installation: compressed length 13.94 in, extended length 21.89 in, stroke 7.86 in, lower mount E2(12X60), upper mount S1(12MM).

Because suspension wear can affect alignment and electronic safety system performance, inspect related components such as tires, brakes, and mounting points during service. Professional installation is recommended for proper fitment and suspension setup.

Quality Assurance

KYB is a major OE shock and strut supplier, and the Excel-G line is produced on the same assembly lines used for original equipment applications. The design uses OE-quality components and factory-style calibration to restore designed suspension performance on the Toyota Prius V.
