Original Aston Martin Vantage Differential

The Aston Martin Vantage differential KY634200AD is a drivetrain component responsible for distributing torque between the driven rear wheels while allowing the wheels to rotate at different speeds during cornering.

A genuine Aston Martin replacement differential can be suitable when the original unit has suffered from mechanical wear, impact damage, bearing noise, internal failure, fluid leakage, or accident-related drivetrain damage.

For a used differential, carefully inspect the photographs for housing cracks, oil leakage, damaged mounting points, corrosion, impact marks, flange damage, and signs of previous repair or installation.

Vantage 2019–2023 Compatibility

The supplied application is for Aston Martin Vantage models from approximately 2019–2023. Differential specifications can vary according to model year, transmission, drivetrain configuration, engine version, final-drive ratio, and factory equipment.

Before ordering, verify the VIN, model year, exact Vantage specification, transmission, rear axle configuration, mounting points, differential identification, and reference KY634200AD.

The part should not be assumed to fit every Vantage simply because the model name is the same.

Differential Assembly

The listing refers to the differential assembly unless additional drivetrain components are specifically shown or stated.

Drive shafts, axle shafts, differential mounts, electronic control units, sensors, propeller shaft, seals, mounting hardware, and transmission components are not included unless clearly shown or specified.

Condition & Inspection

The differential is supplied as an original used component, with the exact condition visible in the product photographs.

Professional inspection is recommended before installation, including checking housing integrity, bearings, seals, fluid condition, backlash, gear condition, mounting points, and compatibility with the vehicle’s final-drive specification.

Installation & Fitment

Installation should be performed by a qualified Aston Martin technician or specialist drivetrain workshop.

Before fitting, compare the replacement differential with the original for dimensions, mounting points, flange configuration, identification number, gear/final-drive specification, and vehicle compatibility.

The differential should be filled with the correct manufacturer-specified lubricant and professionally checked for leaks and correct operation after installation.
