2011 to 2022 Jeep Grand Cherokee Mopar Disc Brake Caliper Assembly Rear Zinc Plated Finish Part Right

This is a Mopar right-hand (passenger side) rear brake caliper for the Jeep Grand Cherokee WK2, model years 2011–2022, specifically for the 3.0L Diesel variant. The caliper features a cast iron housing with a metallic grey finish, and the Pentastar logo is cast into the body. The casting number '4866 RH' is clearly visible, confirming its application. It is equipped with two phenolic pistons, both with intact rubber dust boots, and mounting bolt holes are present. The caliper is used and shows typical surface oxidation and dirt from prior service, but no cracks or structural damage are visible. All visible features match the Mopar 68146612AA specification for this application.
