Bendix Friction SDR5452 Disc Brake Rotor - Rear

Bendix Severe Duty Rotor SDR for Fleet Use

The Bendix Friction Bendix Severe Duty Rotor SDR5452 is a rear disc brake rotor built for demanding truck and fleet service. It combines OEM-style machining standards with severe-duty casting strength to support consistent braking in work-duty and pursuit applications.

Key Features

• Mill balancing and OEM-driven machining specifications for controlled rotor finish and fit
• Focused range for police and fleet vehicles
• OEM vane configurations to match original airflow and heat management geometry
• Manufacturing control with precise machining tolerances
• ACP alloyed-carbon performance castings for thermal stability and strength under severe duty braking

Severe Duty Rotor Line Details

The Bendix Severe Duty Rotor SDR line is aimed at vehicles that see repeated stops, heavier loads, and extended service intervals. For Dodge Ram 1500, Ram 2500, and Ram 3500 rear brake service, SDR5452 follows the brand’s severe-duty approach with machining and casting control focused on durability and brake consistency.

Part number SDR5452 is a rear disc brake rotor for 2003-2008 Dodge Ram 2500 and 2003-2008 Dodge Ram 3500, plus 2006-2008 Dodge Ram 1500 with 8 studs. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Brake pulsation from rotor thickness variation
• Heat-related brake fade during repeated stops
• Uneven braking performance in fleet or work-truck service
• Rotor wear from severe-duty rear axle use
• Fitment issues when replacing a rear rotor on Dodge Ram 1500, Ram 2500, or Ram 3500 applications

Installation Notes and Tips

Compatible with rear brake service only. Verify the vehicle’s stud count before ordering, since 2006-2008 Dodge Ram 1500 applications require 8 studs. Inspect pads, caliper condition, hub surface, and wheel-end hardware during rotor replacement to help maintain even contact and proper braking feel. Confirm the rotor matches the vehicle year, model, and rear position before installation.

Quality Assurance

Bendix Friction manufactures this rotor with controlled machining tolerances, mill balancing, and ACP alloyed-carbon casting construction to support severe-duty braking demands. The OEM vane configuration and machining specifications reflect a focus on repeatable quality for fleet and pursuit use.
