Product Details

The Excel-G product line is KYB’s OE replacement range for drivers who want suspension performance returned to original specifications rather than changed. KYB manufactures this strut on the same OE assembly lines used for original equipment supply, using OE-quality components and calibration intended to preserve the vehicle’s designed ride characteristics. Part number 340017 is a rear suspension strut for 2009-2013 Toyota Matrix and 2009-2010 Pontiac Vibe models.

This part cross-references Monroe Shocks & Struts 72600 for the same application.

What It Helps Address

• Excessive rear bounce or oscillation
• Loose or unstable handling over uneven roads
• Reduced steering response during lane changes
• Uneven tire contact caused by worn damping control
• Noise and vibration from aging rear suspension components

Installation Notes

Fits 2009-2013 Toyota Matrix, rear. Fits 2009-2010 Pontiac Vibe, rear. 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, and a KYB strut boot, part number SB108, to help protect the new strut from dirt, debris, and salt. Verify all mounting dimensions, including compressed length 10.89, extended length 13.79, stroke length 2.9, lower mount type E2(16.1X55), and upper mount type S1(12MM), before installation.
