Proven heavy-duty power for 2018 Ram trucks

This 2018 Cummins 6.7L diesel long block from Houston Engines delivers exceptional torque, efficiency, and reliability for Ram heavy-duty owners. Every unit undergoes complete inspection, pressure and compression testing, and verification of oil and coolant flow integrity. Reman engines include new pistons, bearings, and rings built to factory specifications, while used engines are tested for leak-down and compression balance. Perfect for towing, hauling, or daily driving, this 6.7L long block restores OEM performance with available reman upgrades and warranty-backed dependability, ensuring long-lasting power and durability.

Remanufactured versions of the 6.7L Cummins long block from Houston Engines are fully machined with honed cylinders, resurfaced deck surfaces, reground crankshafts, and reconditioned connecting rods.

Each unit receives new pistons, rings, bearings, and gaskets, along with replaced oil pumps, fasteners, and critical seals. Every engine is torque-checked to maintain consistent compression and oil pressure across all cylinders, while valvetrain geometry and injector sealing are verified before final assembly to ensure factory-grade reliability and long-term durability.

Used 6.7L Cummins long blocks are carefully sourced from low-mileage or well-maintained donor trucks. Each engine undergoes compression, leak-down, and oil analysis testing to confirm internal health and performance integrity. Accessible external seals and gaskets are refreshed, and all critical bolt-ons are inspected for proper operation. Every build is labeled and documented, giving buyers full transparency. Whether reman or used, each Cummins 6.7L long block delivers strong, dependable towing and work-ready power.

Quality verification and warranty assurance

Each engine is thoroughly tested for compression and oil pressure consistency before shipment, ensuring top performance and reliability. All test results are logged by serial number and can be provided upon request to verify internal engine health and quality.

Used 6.7L Cummins engines include limited parts coverage, while reman units feature extended warranty protection for long-term confidence. Detailed break-in and maintenance guidelines are supplied at delivery to preserve warranty eligibility and optimal performance.

To maintain coverage and ensure reliability, proper startup and break-in procedures for your 6.7L Cummins engine are essential. Begin by priming the lubrication system, using the recommended break-in oil, and replacing both the oil and filter according to schedule.

Flush the cooling system thoroughly and replace any contaminated or corroded components such as radiators, thermostats, or EGR coolers. Additionally, inspect the fuel system for water or debris and install a new fuel filter before the first start to prevent injector damage and ensure consistent performance.

During installation, replace all belts, hoses, and coolant to promote optimal operation. If the previous engine experienced a major failure, inspect the turbocharger, intercooler, and charge pipes for oil buildup or metallic residue. Following these essential steps guarantees a smooth break-in process, long service life, and dependable performance under heavy towing or demanding work conditions, preserving true 6.7L Cummins reliability.
