R1 11-19 GMC Sierra 3500 2WD HD Rear Left Drilled Black Brake Rotor

This R1 Concepts rear left drilled brake rotor is built with a solid iron casting, a common material for rotors because it handles heat well and offers good stopping power. The drilled holes are a notable design choice; they help vent gases and heat away from the pad surface, which can lead to more consistent braking performance, especially during repeated stops. This rotor is specifically made for the rear left position on 2011 through 2019 GMC Sierra 3500 trucks with 2WD and heavy-duty configurations.

The black E-coating applied to this rotor isn't just for looks; it helps protect the rotor from rust and corrosion, especially in areas where road salt is common. This coating is designed to wear off the braking surface after the first few applications of the brakes, revealing the iron underneath, but it keeps the non-contact areas looking good. It's a well-built component designed to be a direct replacement for your factory rotor, meaning it fits right without needing modifications.
