Why Buy a 2018 Dodge Engine from Auto Power Source

2018 is the simplest recent Ram 1500 year to buy an engine for. There is one body — the 5-lug DS — so the Classic-versus-New-Style question that complicates 2019 and every year after it does not exist yet, and no 2018 Dodge engine is a 48-volt eTorque build. A 2018 Ram 1500 5.7L is the conventional 12-volt HEMI with a normal alternator. Alongside it the truck offers the 3.6L Pentastar and the 3.0L EcoDiesel V6 (VIN M), the light-duty diesel that shares nothing with the heavy-duty Cummins despite both being called a Ram diesel.

Where 2018 does split is the 5.7L itself, and it is a split many buyers miss: the Ram 2500 was available as a compressed-natural-gas bi-fuel truck, and that engine carries VIN 2 rather than the gasoline VIN T. It is a different long-block specification with its own fuel system, hardened valve seats and calibration — reading the 8th digit of the VIN is the one-step way to tell the two apart before ordering. On the car side 2018 holds three more HEMIs that interchange with neither it nor each other: the 5.7L (VIN T) in Charger, Challenger, Durango and the Ram trucks, the 6.4L 392 (VIN J) in the Scat Pack cars, the new-for-2018 Durango SRT and the gasoline Ram 2500 and 3500, and the supercharged 6.2L (VIN 9) in the Challenger and Charger Hellcats — our 6.2L listings separate the builds carrying Opt XDQ adaptation components from those without. Heavy-duty diesel is the 6.7L Cummins inline-six (VIN L), where pickup and chassis-cab units are built to different option codes inside the same displacement.

Every one of these 38 engines came from a low-mileage donor vehicle, was cataloged by VIN, and is held in our climate-controlled warehouse pending sale. Each unit clears our six-step process: VIN-matched to donor and target, ASE-certified compression test on every cylinder, leak-down evaluation, run-stand noise and smoke verification, full visual inspection of the long-block plus turbo, supercharger and manifolds where present, multi-angle photographs sent for your approval, and palletized freight shipping. The Cummins units get the extra checks: injector-pump pressure, turbo shaft play and grid-heater function; the CNG 5.7L gets its fuel rail and regulator inspected as well. You pay a fraction of dealer-new pricing for identical FCA engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and have 30 days from delivery to return for any reason.
