Product Details

The KYB Excel-G line is calibrated to restore the vehicle’s original suspension behavior using OE-quality components and OE assembly-line manufacturing standards. For Cadillac ATS rear suspension service, SA1018 provides a direct-fit shock and mount assembly that supports consistent damping response, lane-change stability, and controlled stopping performance. This part number SA1018 is a practical choice for drivers and technicians replacing a worn rear right shock on the Cadillac ATS.

What It Helps Address

• Excessive rear-end bounce over bumps
• Reduced stability during cornering or lane changes
• Longer stopping distances caused by worn damping
• Uneven or loose-feeling rear suspension response

Installation Notes

Inspect surrounding suspension components for wear during replacement to ensure the new shock performs as intended. Part number SA1018 is listed as a shock and mount assembly with dust cover included.
