Note regarding Rubicon badged vehicles.

Rubicon badging/decals alone do not confirm Rubicon specification, as some vehicles may have aftermarket or dealer-added decals. Please confirm your vehicle’s VIN/trim and Rubicon-specific hardware before ordering, especially for suspension, steering, axle, driveline, bumper and underbody parts.
