• Premium rubber-steel-rubber shims help reduce noise, vibration, and harshness
• OE-spec cast iron rotor construction with balance and critical-dimension inspection

Product Line Details

The DFC GEOSPEC rotor line focuses on corrosion protection and installation efficiency. The coated surface is designed to resist rust better than conventional paint or zinc finishes, while the dry packaging helps reduce prep time during brake service. The 5000 Advanced Brake Pads line is formulated for consistent friction output and uses shims to support quieter operation.

Detailed Description

Part number 4502-40159 is a rear brake service kit for Ram 3500 trucks that need a rotor-and-pad replacement at the rear axle. It is engineered for 2022 Ram 3500 rear 12-inch rear axle applications and 2019-2021 Ram 3500 rear SRW models with the high output HD transmission and 12-inch rear axle. The coated rotors are machined to tight tolerances, finished non-directionally, and inspected for balance and OE-spec dimensions. The brake pads are post-cured, scorched, and assembled with premium shims to support consistent pedal response and reduced NVH. This part number, 4502-40159, is a direct service solution for Ram 3500 rear brake maintenance.

What This Brake Kit Helps Address

• Rear brake pulsation caused by worn or uneven rotors
• Brake noise from aged pads or inconsistent pad contact
• Rust buildup on exposed rotor surfaces
• Extended brake service time from rotors that require cleaning before installation
• Reduced stopping consistency from worn rear brake components

Installation Notes and Tips

Compatible With 2022 Ram 3500, rear, 12" rear axle. Compatible With 2019-2021 Ram 3500, rear, SRW with high output HD transmission and 12" rear axle. Verify axle configuration and rear brake dimensions before installation. Clean the hub mounting surface, inspect caliper hardware and brake hoses, and follow the vehicle manufacturer’s torque specifications during service. The rotor coating is removed naturally by the brake pads during normal operation.

Quality Assurance

DFC GEOSPEC rotors are manufactured to OE specifications, inspected for critical dimensions, and covered by a 12-month warranty against defects in material and workmanship. The brake pads are post-cured and scorched for stable friction performance, with premium shims added for improved NVH control. Part number 4502-40159 is built for consistent rear brake service on Ram 3500 applications.
