Product Line Details

Excel-G is KYB’s OE replacement line for drivers who want factory-style suspension behavior rather than a changed ride feel. The 340018 is assembled on KYB OE production lines using OE-quality components and calibrated to restore the vehicle’s original damping characteristics. For Toyota Corolla rear strut replacement or Toyota Matrix rear suspension service, this line is built around original control and handling targets.

Detailed Description

KYB 340018 is a rear suspension strut for select 2009-2014 Toyota Corolla and Toyota Matrix models, plus 2009-2010 Pontiac Vibe applications. It is engineered to restore the vehicle’s original ride control, braking stability, lane-change response, and handling balance. This part cross-references Monroe Shocks & Struts 72599 for the same application. The Excel-G design uses OE-style calibration, a nitrogen gas charge, and a twin-tube layout to support consistent damping performance in everyday driving.

What It Helps Address

• Excessive rear-end bounce after bumps
• Loose or unstable handling in turns and lane changes
• Reduced braking stability caused by worn rear struts
• Uneven tire contact from weak damping control
• Noisy or inconsistent suspension response from worn OE struts

Installation Notes and Tips

For 2012-2013 Toyota Corolla, 2009-2010 Toyota Corolla, and 2009-2010 Pontiac Vibe applications, replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends new strut mounts, part number SM5382, to reduce noise and vibration. A KYB strut boot, part number SB108, can help protect the strut from dirt, debris, and salt. The listed dimensions are compressed length 12.57, extended length 17.02, and stroke length 4.45.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers, and the Excel-G line is built on the same OE assembly lines using OE-quality components. The 340018 is classified as an Original Equipment for the Aftermarket replacement intended to return the suspension to designed performance.
