A “crate engine” is a brand-new unit delivered straight from the producer (Mopar) or a licensed builder.

Pros: Zero miles, latest technical updates, complete manufacturer guarantee.
Cons: The most pricey alternative.

Remanufactured Engines

A remanufactured engine is one that has actually been entirely disassembled, cleaned, and checked. Any used parts are replaced with new components, and the engine is machined to factory specifications.

Pros: High dependability, often comes with a 1-to-3-year service warranty, considerably cheaper than new.
