Description
Upgrade your GM truck or SUV with Baer’s 15" Extreme+ Rear Brake Kit in Silver, delivering motorsport-inspired braking power with refined aesthetics.

The large 15-inch, 2-piece rotors are vented, slotted, drilled, and zinc-plated for maximum cooling and corrosion resistance, featuring billet aluminum rotor hats and pre-assembled with aerospace-grade hardware.
