Bentley GT GTC Shock Absorber Left Right Rear 975513035J

Part Number: 975513035J (Supersedes 975513035C) Series: 3S / 3SD (Third Generation: 2018–2024+) Platform: MSB Platform (Shared with Porsche Panamera 971)

The part number 975513035J refers to the rear gas-filled shock absorber for the third-generation Bentley Continental. Unlike the first two generations, which often used integrated air struts, this generation features a separate CDC (Continuous Damping Control) shock absorber that works in tandem with a standalone air spring.

1. Key Specifications

• Position: Rear (Fits both Left and Right sides).

• Technology: Equipped with an electromagnetic solenoid for Continuous Damping Control (CDC), allowing the car to switch between “Bentley,” “Comfort,” and “Sport” modes in milliseconds.

• Spring Type: Designed specifically for vehicles with Air Suspension.

• Mounting Type: Features a Top Yoke and Bottom Fork mounting style.

2. Component Identification

• OEM Part Numbers: 975513035J is the latest revision. You may also find it listed under 975513035C or 975513035D in earlier parts catalogs.

• Interchange: While this part is shared with the New Flying Spur (2020+), the damping rates (software calibration) are specifically tuned for the shorter wheelbase and weight distribution of the GT/GTC.

3. Common Symptoms of Failure

• Leaking Oil: If you see hydraulic fluid on the shock body or the driveway, the internal seals have failed.

• “Suspension Fault” Warning: A dashboard error often indicating that the CDC solenoid valve has an electrical fault or is disconnected.

• Excessive Bouncing: If the rear of the car feels “loose” or continues to bounce after a speed bump, the gas pressure or damping capability is depleted.

• Knocking Noise: Often caused by worn internal valving or a perished upper mounting bush.

4. Service & Installation Advice

• Replace in Pairs: Bentley and suspension manufacturers strongly recommend replacing rear shocks in pairs to ensure balanced handling and consistent damping performance across the axle.

• Air Spring Distinction: Remember that 975513035J is just the shock absorber. If your car is sagging overnight, the problem is likely the Air Spring (3S0616001), not this shock absorber.

• Calibration: After installation, it is recommended to perform a “Suspension Adaptation” using a diagnostic tool (ODIS) to ensure the CDC module recognizes the new hardware’s resistance values.
