Hydraulic Power Brake Booster Fit For Ram 2500 3500 4500 5500 2011-18 52013874AE

When your RAM 2500, 3500, 4500, or 5500 starts demanding extra leg effort at the brake pedal — or worse, lets the pedal sink toward the floor — every mile driven is a liability. This direct-fit hydraulic power brake booster is engineered to restore factory-level stopping confidence to your heavy-duty RAM, whether you're hauling a full gooseneck, managing a loaded flatbed, or running daily fleet routes that can't afford downtime. COMPATIBILITY This hydraulic brake booster is a verified direct replacement for 2011, 2012, 2013, 2014, 2015, 2016, 2017, and 2018 RAM 2500, 3500, 4500, and 5500 trucks. It cross-references OE part number 52013874AE, giving you a fast, reliable way to confirm fitment against your existing unit. These heavy-duty RAM platforms rely on a hydraulic assist system — not a conventional engine-vacuum setup — making this booster the correct solution for diesel-equipped models including those running the legendary 6.7L Cummins turbodiesel. Always verify your cab configuration (Regular, Crew, Chassis Cab), engine designation, and existing OE part number before ordering to guarantee a proper match. This unit is not compatible with vacuum-style brake systems. KEY BENEFITS • Eliminates brake pedal sink, excessive effort, and inconsistent stopping distances caused by a failed or degraded booster unit • Hydraulic power design purpose-built for heavy-duty RAM trucks that do not use a conventional vacuum brake booster • OE-matching mounting dimensions, port locations, and pushrod geometry allow for a drop-in installation that minimizes shop time and labor cost • Cross-references OE part number 52013874AE for confident, mistake-free fitment verification before you even open the box • Restores factory braking feel and full pedal response so your RAM performs safely under maximum tow weight and payload • Ideal for work trucks, fleet managers, and commercial operators where brake system reliability directly impacts safety and scheduling TECHNICAL SPECIFICATIONS • OE Cross-Reference Part Number: 52013874AE • Brake Assist Type: Hydraulic power (not vacuum-based) • Compatible Engine: 6.7L Cummins turbodiesel and other RAM HD engine configurations using hydraulic brake assist • Vehicle Fitment: 2011-2018 RAM 2500, 3500, 4500, 5500 • Port Configuration: Matches OEM hydraulic line inlet and outlet locations for direct connection • Pushrod Geometry: OE-spec pushrod length and diameter for correct master cylinder actuation • Mounting Pattern: Direct bolt-on to factory firewall bracket; no modification required • Condition: New aftermarket replacement unit MATERIALS AND BUILD QUALITY This hydraulic brake booster is constructed to withstand the thermal cycling, hydraulic pressure fluctuations, and mechanical stress that heavy-duty RAM trucks generate day in and day out. The booster housing is manufactured from heavy-gauge steel and precision-cast components designed to maintain structural integrity under sustained hydraulic pressure loads that far exceed what a standard light-duty brake booster would encounter. Internal seals and bore surfaces are finished to tight tolerances to prevent fluid bypass and pressure loss — the two root causes of soft or sinking pedal feel. All hydraulic ports are machined to OE thread specifications, ensuring leak-free connections with your existing brake lines without the need for adapters or thread chasing. This unit is built to function in demanding commercial environments: construction sites, agricultural operations, towing services, and high-mileage fleet routes where brake system failures are simply not an option. INSTALLATION GUIDE Before beginning, gather a basic set of hand tools including a combination wrench set, brake line wrench, socket set, and clean brake fluid or hydraulic fluid per your RAM's service specification. Ensure the engine is off and the system pressure is fully relieved before disconnecting any hydraulic lines. Step 1: Disconnect the battery to eliminate any accidental electrical interference during the repair. Step 2: From inside the cab, remove the driver's knee bolster panel to access the brake pedal pushrod clevis pin — remove the pin and separate the pushrod from the pedal. Step 3: Under the hood, use a brake line wrench to carefully disconnect the hydraulic supply and return lines from the booster; cap lines immediately to prevent fluid contamination. Step 4: Remove the four mounting nuts securing the booster to the firewall — a deep socket or box wrench works best in the tight firewall clearance. Step 5: Withdraw the old booster through the engine bay. Step 6: Position the new booster onto the firewall studs and thread the mounting nuts to OEM torque specification. Step 7: Reconnect the hydraulic lines, torquing fittings snugly to prevent leaks. Step 8: Reconnect the pushrod to the brake pedal clevis and reinstall the retaining pin. Step 9: Reconnect the battery, check and top off the hydraulic fluid reservoir, then bleed the system per RAM HD service procedure. Step 10: Start the engine, pump the brake pedal several times, and verify firm, consistent pedal feel before returning the vehicle to service. Professional installation is always recommended for brake system components.
