Product Details

KYB Excel-G is part of KYB’s OEA, or Original Equipment for the Aftermarket, line. It is manufactured on KYB OE assembly lines using OE-quality components and calibrated to restore factory-designed performance rather than alter it.

This part also cross-references Monroe Shocks & Struts 172286 for the same application.

What It Helps Address

• Excessive bouncing after bumps
• Loose or unstable rear suspension feel
• Reduced braking stability caused by worn damping
