The factory brake pads on your 2004.5-2005 GM 6.6L Duramax LML perform adequately for everyday driving, but their effectiveness diminishes under heavy-duty towing, intense off-roading, or any activity beyond standard street use. Fortunately, upgrading is simple with our premium performance brake pads available at Alligator Performance. Enhance your GM 2500/3500's stopping power and fade resistance while generating significantly less dust than the stock pads. These brake pads fit directly in place of your truck's factory pads, making for a quick and cost-effective upgrade for your custom GM 6.6L Duramax build.
