The Power Stop Evolution drilled and slotted zinc-plated rotor pair is a rear brake upgrade for 2011–2012 Ram 3500 applications. Precision cross-drilling and rounded slots help cool the rotor and sweep away gasses, dust and moisture to preserve pad contact. Zinc plating resists corrosion, and these rotors are manufactured to strict tolerances, dynamically balanced, and intended as a direct-fit, bolt-on replacement sold as a pair.
