Product Details

DFC’s GEOSPEC rotor line is built around OE-style fit, machining precision, and corrosion protection. Each rotor is processed dry and shipped ready to install, which helps reduce prep time during a rear brake job. The 5000 Advanced pads are formulated for consistent friction, with post-curing and scorching steps used to reduce initial break-in demands and support stopping response from the first stop. This kit is a practical choice for owners servicing a Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500 HD, GMC Sierra 2500 HD, GMC Sierra 3500 HD, or Chevrolet Suburban 3500 HD rear axle brake system.

What This Brake Kit Helps Address

• Rear brake pulsation from worn or uneven rotors
• Reduced stopping performance from worn pads
• Brake noise caused by aged pad friction material
• Rust buildup on exposed rotor surfaces
• Longer service time caused by rotors that require cleaning before installation
