Product Line Details: Power Stop Rear Drilled, Slotted and Zinc Plated Brake Rotor Pair

This Power Stop product line focuses on rear brake rotors that combine drilled and slotted surface features with a zinc plating finish. The drilled and slotted design helps reduce brake fade by improving heat dissipation and allowing gases and debris to escape during braking. Zinc plating adds a layer of rust resistance, extending rotor life especially in environments prone to moisture exposure. This rotor pair is vented, which further aids in cooling during heavy braking conditions, making it suitable for the Ford F-150 rear brake setup.

Technical Specifications and Features

The AR85148XPR rotor set features a vented rotor type with a nominal thickness of 25.00 mm and a discard thickness of 23.00 mm, ensuring safe replacement intervals. The overall height measures 79.90 mm, and the outside diameter is 348.00 mm, matching the Ford F-150 rear brake requirements. The surface is both drilled and slotted, enhancing braking efficiency by improving pad contact and reducing heat buildup. The zinc plating provides a rust-resistant coating to maintain rotor integrity over time. The mounting bolt hole circle diameter is 135.00 mm with 6 lug holes, ensuring proper fitment and secure installation.
