StopTech's drilled and slotted rear left rotor for 2007–2010 GMC Sierra (with rear drum) and 2007–2009 GMC Yukon is a one-piece direct replacement that improves bite and helps evacuate heat, dust and gasses. The rotor's slotting and cross-drilled pattern reduce pad glazing and wet-weather degradation, while a protective black e-coating and tuned metallurgy enhance corrosion and thermal-crack resistance.
