Rear Brake Kit for Ram 1500, 2500, 3500

The Dynamite Friction DFC GEOSPEC Rotors with 5000 Advanced Brake Pads kit is a rear disc brake service kit built for select Dodge Ram trucks. It combines coated rotors and advanced friction pads in one package for a straightforward brake refresh on rear axle applications.

• Rear disc brake kit with rotors and pads
• DFC GEOSPEC coated rotors with silver-gray corrosion-resistant finish
• Dry-to-install rotor coating reduces prep time during brake service
• Non-directional rotor finish supports even pad bed-in and smoother braking
• 5000 Advanced pads are post-cured and scorched for stable friction performance
• Premium rubber-steel-rubber shims help reduce noise, vibration, and harshness
• OE-style rotor casting and machining for durability and fit consistency

DFC GEOSPEC Rotors and 5000 Pads

Part number 4502-40138 is part of the DFC GEOSPEC Rotors with 5000 Advanced Brake Pads line, which pairs coated brake rotors with a pad formulation developed for consistent friction characteristics across a range of vehicle applications. For rear brake service on Dodge Ram 1500, Ram 2500, and Ram 3500 trucks, this kit brings together components engineered to work as a matched set. The rotors are machined to tight tolerances, inspected for balance, and finished to OE specifications, while the pads are prepared to reduce initial break-in and support quieter operation.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

• Reduced stopping performance from heat-worn friction material
• Rust buildup on exposed rotor surfaces
• Extended brake service time when rotors require extra cleaning before installation

Installation Notes and Quality Assurance

Install on the rear axle only for the listed Dodge Ram applications. The rotors are shipped dry and ready to install, with no additional cleaning step required before service. After installation, follow the vehicle manufacturer’s brake bedding procedure to help establish even pad transfer and stable braking performance.

Each rotor is manufactured to OE specifications, then inspected for critical dimensions and balance. DFC includes a 12-month warranty against defects in material and workmanship on the rotors. Part number 4502-40138 is intended for direct-fit rear brake service on the listed Ram truck applications.
