The Power Stop Evolution drilled and slotted zinc-plated rotor pair is a rear upgrade for 2009–2020 GMC Savana 4500 applications. Precision drilling and rounded slots enhance cooling and remove gases, dust, and moisture for cleaner pad contact, while silver zinc dichromate plating offers additional corrosion resistance. These rotors are dynamically balanced and fit as a direct OE-style bolt-on replacement.
