KYB 345055 Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber

The KYB Excel-G 345055 is a rear suspension shock absorber built to restore original ride control on select Chevrolet, GMC, Saturn, Pontiac, and Suzuki applications. It is a nitrogen gas-charged, twin-tube design made on KYB OE assembly lines with OE-quality components for a direct replacement approach.

For drivers searching for a rear shock for a 2005-2017 Chevrolet Equinox or a rear shock absorber for a 2010-2017 GMC Terrain, the Excel-G line is calibrated to return factory-style handling, braking stability, and lane-change response without changing the vehicle’s intended suspension behavior.

• KYB recommended OEM replacement shock for SUVs and crossovers
• Restores designed control, handling, and body movement management
• Triple-lip fluid seal helps reduce oil and gas leakage
• Vehicle-specific, hand-assembled damping valves manage tire contact and steering response
• Supports proper operation of electronic safety systems by maintaining suspension performance as engineered
• Strong strut body and bracket construction helps minimize flex and maintain alignment
• Dust cover included

Excel-G Product Line Details

KYB Excel-G is an Original Equipment for the Aftermarket (OEA) line focused on restoring factory ride characteristics rather than altering them. Part number 345055 uses the same OE-quality manufacturing approach KYB supplies to new vehicle manufacturers, making it a practical choice for rear suspension service on the Chevrolet Equinox, GMC Terrain, Pontiac Torrent, Saturn Vue, and Suzuki XL-7.

This part cross-references Monroe Shocks & Struts 911258 for the same application.

What This Shock Absorber Helps Address

• Excessive rear bounce or oscillation
• Loose or unstable rear-end handling over bumps
• Reduced braking stability caused by worn rear shocks
