2013-2017 Ram 1500 RAM EZH 5.7L V8 Remanufactured Engine

Description

Meet strict commercial truck fleet maintenance benchmarks with 485 lbs of precision-machined powertrain engineering that outputs dependable V8 pulling power and active thermal control throughout the RAM 1500 EZH 5.7L Remanufactured Engine engineered for 2013 to 2017 RAM 1500 commercial pickup trucks. This Eagle HEMI V8 with variable cam timing and MDS restores massive pulling torque across demanding vocational routes.

Engineered from high-density cast iron, this Eagle-series deep-skirt block incorporates cross-bolted four-bolt main bearing caps with side cross-bolts that halt bottom-end distortion under load. A nodular cast iron crankshaft pairs with forged powdered metal cracked rods and hypereutectic aluminum pistons with anti-friction skirt coatings. Cylinders feature diamond plateau crosshatch honing below an Ra 30 deck finish for MLS gasket sealing. Dry weight registers at 485 lbs with a 7.0-quart capacity steel oil pan.

Key Features of RAM 1500 EZH

Vocational fleet supervisors buy RAM 1500 EZH remanufactured engine packages to keep municipal utility trucks, service flatbeds, and equipment haulers in continuous operation. Every remanufactured long block undergoes vacuum decay testing to guarantee total fluid circuit separation before crate departure.

• Eagle cylinder heads feature reshaped high-flow ports to maximize airflow and torque output
• Camshaft phaser mechanisms continuously adjust valve timing to broaden low and high RPM power
• Multi-Displacement System solenoids deactivate four cylinders during cruise to reduce fuel consumption
• 0.0011 to 0.0019 inch main bearing clearances maintain solid hydrodynamic lubrication film strength
• Multi-layer steel cylinder head gaskets maintain combustion seals across extreme summer transit heat
• High-pressure internal gerotor oil pumps channel positive lubrication to hydraulic roller lifters
• Dynamic rotating balancing protects RAM 1500 EZH driveline parts from harmonic strain

RAM EZH Truck Operational Limits

Operating lubricant pressure produces 25 to 30 PSI during warm idle and expands to 50 through 65 PSI at 2400 RPM cruise speeds. Thermostats regulate internal coolant flow between 195°F and 210°F to stabilize combustion heat transfer. This 5.7-liter Eagle HEMI V8 outputs 395 horsepower at 5600 RPM and 410 lb-ft continuous torque at 3950 RPM with a 10.5:1 compression ratio. Cylinder cranking pressure measures between 175 and 190 PSI across all eight chambers. The cooling system rejects 4500 BTU per minute during full-throttle loaded climbs.

RAM EZH Crankshaft Alignment Specs

An 8-bolt rear crankshaft flange mounts flush to factory TorqueFlite 8-speed automatic transmission flexplates. Measured crankshaft thrust endplay checks out between 0.0030 and 0.0070 inches. The 1.250-inch front crankshaft snout features a single keyway to position the timing crank sprocket and harmonic balancer, holding true accessory drive serpentine belt pulley alignment.

RAM EZH Fleet Servicing Protocols

Technicians must pre-lube the engine through the oil filter adapter port to charge the hydraulic lifters and VVT phaser before initial ignition startup. Use 5W-20 motor oil meeting Chrysler MS-6395 standards to guarantee proper MDS operation. This commercial engine is not engineered for aftermarket turbochargers exceeding 6 PSI boost, nitrous injection, or tractor pull competition.

• Inspect engine oil level and coolant recovery tank fluid each shift before vehicle dispatch
• Drain break-in motor oil and install fresh oil filter after 500 initial road miles
• Change crankcase motor oil and replace filter every 3500 miles during severe fleet duty

RAM EZH Commercial Warranty Manifest

Commercial fleet purchasers receive a 3-Year / 100,000-Mile commercial fleet warranty covering structural casting and internal moving components. The heavy-duty crate contains one remanufactured long block engine, a complete engine install gasket set, spark plug well seals, front timing cover seals, dyno test documentation, and priming instructions.
