The R1 Concepts Geo-Carbon drilled-and-slotted rotor is a replacement brake rotor for Chevrolet Silverado 3500 HD (2011–2019), specified for the rear left position. The rotor’s drilled holes and slots help channel debris and gases away from the pad contact area to support consistent braking feel. Sold as a single rotor for the designated wheel position, it serves as a like-for-like replacement during brake service.
