Fitment & Compatibility
Verify the housing-end drawing and axle offset before selecting this kit. The modified-vehicle examples in the table below do not identify the installed rear axle from a model name or front-spindle option. DS-120 labels a 2.81-inch offset while the current kit page lists 2.91 inches; have Wilwood confirm the required configuration from measurements before ordering. A generic cable note does not add a parking-brake mechanism to this assembly.
