KYB Excel-G Rear Shock for Avalanche 1500

KYB Excel-G 344436 is a rear suspension shock absorber built to restore original ride control, stability, and steering response on the Chevrolet Avalanche 1500. It is a direct OE-style replacement for drivers who want factory-correct damping rather than a changed ride feel.

Fits 2002-2006 Chevrolet Avalanche 1500, rear, including off-road chassis package applications and excluding Premium Smooth Ride Suspension.

Product Details

The KYB Excel-G line is built on KYB OE assembly lines using OE-quality components and calibration targets that match the vehicle’s original suspension behavior. Part number 344436 is engineered for the rear position on the Chevrolet Avalanche 1500 and is classified by KYB as an Original Equipment for the Aftermarket (OEA) replacement. This makes it a practical choice when the goal is to restore factory ride control, braking stability, lane-change response, and handling balance without altering the vehicle’s intended suspension feel.

This part cross-references Monroe Shocks & Struts (e.g., 911506) for the same application.

Common Issues This Shock Can Address

• Excessive rear bounce after bumps or dips
• Reduced stability during braking or lane changes
• Loose or unsettled rear suspension feel
• Uneven tire contact caused by worn damping
• Loss of factory-like ride control on a Chevrolet Avalanche 1500

Installation Notes and Tips

Verify rear-position fitment before ordering: Fits 2002-2006 Chevrolet Avalanche 1500, rear. Confirm the vehicle is not equipped with Premium Smooth Ride Suspension, since that configuration is excluded. The listed dimensions include a compressed length of 14.4 in., extended length of 23.62 in., and stroke length of 9.22 in. Match the upper and lower mount type to the original setup during installation.
