Product Line Details: Power Stop Rear Drilled, Slotted and Zinc Plated Rotors

This Power Stop - Rear Drilled, Slotted and Zinc Plated Brake Rotor Pair belongs to a product line focused on improving braking efficiency through enhanced rotor surface design and protective coatings. The drilled and slotted surface helps to dissipate heat and reduce brake fade, while the zinc plating provides a rust-resistant barrier to maintain rotor integrity over time. This combination is particularly suited for rear brake applications on Jeep vehicles requiring reliable stopping power under varied driving conditions.

Technical Description and Specifications

The AR8793XPR rotor set features a solid rotor type constructed to meet the exacting standards of Jeep Commander and Grand Cherokee rear brake assemblies. The drilled and slotted surface pattern improves water and gas evacuation during braking, which helps maintain consistent pad contact and reduces the risk of brake fade. The zinc plating offers corrosion resistance, extending the rotor’s lifespan in environments prone to moisture and road salt exposure. With a nominal thickness between 12.50 mm and 14.00 mm and a discard thickness of 0.49 inches (12.50 mm), these rotors ensure safe replacement intervals. The mounting bolt hole circle diameter of 127.00 mm and 5 lug holes provide secure installation compatibility with the specified Jeep models.
