KYB 345073 Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber

The KYB Excel-G 345073 is a rear suspension shock absorber built to restore original ride control, stability, and handling. It is a nitrogen gas-charged, twin-tube design made on KYB OE assembly lines with OE-quality components for GM truck and SUV applications.

• Part number 345073 for direct catalog identification

Product Details

Excel-G is KYB’s Original Equipment for the Aftermarket line, focused on restoring the vehicle’s designed suspension behavior rather than changing it. For GM truck and SUV rear applications, this shock absorber is calibrated to support controlled rebound, stable lane changes, and consistent braking response. The KYB Excel-G 345073 is a practical OE-style replacement for drivers servicing a Cadillac Escalade, Chevrolet Tahoe, GMC Yukon, or related platform where the original suspension feel needs to be brought back.

This part cross-references Monroe Shocks & Struts 911506 for the same application.

What It Helps Address

• Excessive rear bounce after bumps or dips
• Loose or unsettled handling in lane changes
• Reduced braking stability caused by worn rear shocks
• Uneven tire contact from weak damping control
• Suspension noise or fluid leakage from aging shock absorbers

Installation Notes

Verify rear fitment by suspension package before ordering. This shock is listed for vehicles without electronic adjustable suspension, ZW7 premium smooth ride suspension, or police package where noted. Confirm compressed length, extended length, and mount type against the original part before installation. Professional installation is recommended, and the suspension should be inspected for worn bushings, mounts, and related hardware during replacement.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers, and Excel-G is produced on the same OE assembly lines using OE-quality components. The design is intended to restore original suspension performance for the listed GM rear applications, including 2007-2014 Chevrolet Tahoe, 2007-2014 GMC Yukon, and 2008-2014 Cadillac Escalade models.
