Description

The 2013-2021 Dodge Ram 1500 5.7 Hemi Engine EZC MDS is part of Chrysler’s well-known HEMI engine family, a lineup of V8 engines designed to deliver strong performance and dependable durability for trucks and performance vehicles.

The 5.7-liter HEMI engine is widely recognized for its hemispherical combustion chamber design, which improves airflow and combustion efficiency. This design allows the engine to produce strong horsepower while maintaining reliable operation under demanding driving conditions.

Ram trucks equipped with the 5.7 HEMI engine benefit from excellent towing capability, strong acceleration, and dependable power delivery. Because of its robust construction and proven design, this engine has become one of the most popular powertrains used in full-size pickup trucks.

The EZC engine code refers to the specific configuration used in Ram 1500 trucks equipped with the Multi-Displacement System.

What MDS Technology Does

The 2013-2021 Dodge Ram 1500 5.7 Hemi Engine EZC MDS features Chrysler’s Multi-Displacement System (MDS), which improves fuel efficiency by temporarily deactivating four cylinders during light driving conditions.

When the vehicle requires less power, the system automatically switches the engine from eight cylinders to four cylinders. When additional power is needed, the engine seamlessly returns to full V8 operation.

This technology helps drivers benefit from the power of a V8 engine while improving fuel economy during highway driving and low-load conditions.

Every engine we sell is fully remanufactured to meet or exceed OEM specifications:

• Deep Clean – To start the remanufacturing process, every engine is fully disassembled and hot tanked (cast iron) or thermally cleaned (aluminum)
• Inspection – Magnaflux testing uses magnetic particles to inspect metal, checking for microscopic cracks and fissures that will cause long-term failure. All parts are visually inspected as well.
• Machining and New Parts – Deck surfaces are CNC machined and new parts are added. New parts inlcude bearings, pistons, rings, lifters, oil pump, gaskets, Viton™ valve seals, freeze plugs, galley plugs and either a new timing chain (with new tensioners) or a new timing belt (with new tensioner). If an engine has a timing-driven water pump, a new pump is installed.
• SIM Testing – Each engine is SIM tested after reassembly, with the cooling and oil systems being fully pressurized and the crank being spun at high RPM to verify compression and build quality.

Because of our rigorous remanufacturing process, we can offer the industry’s best warranties. Each engine comes with up to 7 years and 1 million miles of warranty, which can be upgraded to include Pure Care™ no-fault protection. No other engine manufacturer comes close.
