Replace or upgrade the worn brake rotors on your 2004.5-2005 Chevy/GMC 6.6L LLY Duramax today. Offered as stock replacements or as upgraded units, brake rotors are available that can help improve braking performance. Slotted and drilled rotors offer improved heat dissipation and allow brake gases formed to escape. Upgraded rotors are available with coatings for improved corrosion resistance and some are even treated to help them 1last longer than the OE rotor. With a wide range to fit many budgets, you can find what you need for your vehicle. Brake rotors wear out over time, just like brake pads. When they are below the manufacturer's recommended thickness they need to be discarded and replaced. XDP offers the leading brake brands such as Dorman, StopTech, and more!
