Product Details

DFC’s GEOSPEC rotor and 5000 Advanced pad combination is built for drivers who want a matched rear brake service package instead of sourcing components separately. The rotors are machined to tight tolerances, inspected for critical dimensions, and finished to support consistent braking performance. The coated surface helps resist rust better than conventional painted or zinc-coated rotors, while the dry packaging means the rotors are ready for installation without cleaning off oil.

The pad set is formulated for axle-specific braking demands and is processed to reduce initial break-in time. For Chevrolet Silverado 3500 HD and GMC Sierra 3500 HD rear brake service, this kit provides a straightforward replacement option that aligns with OE-style fitment and performance expectations. Part number 4502-48128 is a practical choice for rear brake maintenance on these heavy-duty trucks.

What This Brake Kit Helps Address

• Rear brake wear on high-mileage Silverado 3500 HD and Sierra 3500 HD trucks
• Rotor rust and surface corrosion on exposed brake components
