KYB 339016 Suspension Strut - Front

KYB Excel-G Front Strut for GM Ride Control

The KYB Excel-G 339016 is a front suspension strut built to restore original ride control, stability, and steering response. It is an OE-style replacement for select Cadillac Seville and Oldsmobile Aurora applications, with calibration focused on factory handling characteristics rather than changing the vehicle’s feel.

Key Features

• KYB recommended OEM replacement strut
• Nitrogen gas-charged, twin-tube design
• Vehicle-specific, hand-assembled damping valves for tire contact and body control
• Triple-lip fluid seal to reduce oil and gas leakage
• Strong strut body and bracket construction to help maintain alignment under load
• Internal rebound spring and R-stop design
• Compatible with electronic safety systems that rely on suspension geometry and tire contact

Product Details

KYB Excel-G is KYB’s OEA-style replacement line, produced on the same OE assembly lines and using OE-quality components. This front strut is engineered to restore the designed performance of the suspension on 1998-2004 Cadillac Seville and 1998-1999 Oldsmobile Aurora front applications. The KYB 339016 is a practical choice when the goal is to return the vehicle to factory-like ride control, lane-change response, and braking stability without altering the original suspension tuning. This part cross-references Monroe Shocks & Struts 71684 for the same application.

What It Helps Address

• Excessive front-end bounce or float
• Reduced steering response during lane changes
• Uneven tire contact caused by worn damping
• Noise or vibration from a fatigued front strut
• Loss of factory ride control on Cadillac Seville and Oldsmobile Aurora front suspension systems

Installation Notes

Fits 1998-2004 Cadillac Seville, front. Fits 1998-1999 Oldsmobile Aurora, front. For the Oldsmobile Aurora application, replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends new strut mounts, part number SM5276, to reduce the chance of noise and vibration. Verify electronic adjustable suspension equipment before installation on Seville models, since this application excludes that system.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers, and the Excel-G line is built to OE-quality standards on KYB production lines. The 339016 is calibrated to restore original suspension behavior for the listed GM applications and is backed by KYB’s OE-focused manufacturing approach.
