Rear Brake Kit for Heavy-Duty GM and Hummer Applications

Dynamite Friction DFC GEOSPEC Coated Rotors with 3000 Ceramic Brake Pads and Hardware Kit, part number 4312-48019, combines coated rear rotors, ceramic pads, and matching brake hardware for select Chevrolet, GMC, and Hummer vehicles. It is built for drivers who want consistent rear braking performance, reduced brake dust, and corrosion-resistant rotor surfaces.

Key Features

• DFC 3000 ceramic brake pads for stable friction across a wide temperature range
• Low-dust pad formulation for cleaner wheel maintenance
• Post-cured and scorched pads for more consistent initial braking response
• Premium rubber-steel-rubber shims for improved noise, vibration, and harshness control
• GEOSPEC coated rotors with a silver-gray finish that resists rust better than conventional paint or zinc coatings
• Dry-shipped rotors ready for installation without oil removal
• Non-directional rotor finish for smoother pad bed-in and quieter stops
• Hardware kit uses PTFE coating, vulcanized rubber, and stainless steel construction

Product Details

The 4312-48019 brake kit is engineered for rear brake service on applications such as Chevrolet Silverado 1500 HD, GMC Sierra 1500 HD, Chevrolet Suburban 2500, GMC Yukon XL 2500, and Hummer H2. The DFC GEOSPEC coated rotors are machined to OE-style tolerances, inspected for critical dimensions, and processed with a non-directional finish to support even pad contact. The 3000 ceramic pads are formulated for passenger and light-duty truck use, with low copper content to meet California and Washington requirements for 2021/2025 restrictions. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Brake Kit Helps Address

• Rear brake noise from worn or fatigued hardware
• Uneven pad wear caused by corroded or weakened brake clips
• Brake dust buildup on wheels
• Rotor rust on exposed braking surfaces
