KYB 349125 Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber

KYB Excel-G part number 349125 is a rear suspension shock absorber built to restore original ride control, stability, and handling. It is a direct-fit replacement for select Buick Enclave, Chevrolet Traverse, GMC Acadia, GMC Acadia Limited, and Saturn Outlook applications.

The Excel-G line is KYB’s OE-style replacement series, produced on KYB assembly lines with OE-quality components and calibrated to return the vehicle to its designed damping characteristics rather than change them.

Key Features

• Nitrogen gas-charged, twin-tube shock absorber design
• Vehicle-specific damping calibration for original ride control
• Triple-lip fluid seal to reduce oil and gas leakage
• Hand-assembled, in-house damping valves for consistent response
• Strong strut body and bracket construction to help maintain alignment under load
• Dust cover included
• R-stop included for added suspension control

Detailed Product Overview

KYB Excel-G 349125 is engineered for rear suspension service on GM crossover and SUV platforms where ride quality, braking stability, lane-change response, and body control matter. With a compressed length of 10.63 inches, extended length of 15.94 inches, and 5.31 inches of stroke, this shock is sized for the specified rear applications and uses E2 lower and upper mount types for proper installation. The design focuses on restoring the vehicle’s original suspension behavior, which is important for systems that rely on suspension, brakes, and tires working as the manufacturer intended.

This part cross-references Monroe Shocks & Struts 37315 for the same application. KYB 349125 is a practical OE-style replacement for drivers servicing a rear shock on a Buick Enclave, Chevrolet Traverse, or GMC Acadia platform.

What It Helps Address

• Excessive rear bounce after bumps
• Reduced stability during braking or lane changes
• Loose or unsettled rear suspension feel
• Uneven tire contact caused by worn damping
• Oil or gas leakage from an aging shock absorber
