Remanufactured Engines

A remanufactured engine is one that has been totally taken apart, cleaned up, and rebuilt to initial equipment manufacturer (OEM) specs. Worn parts are changed with brand-new parts.

Pros: Reliable, typically features a 3-to-5-year warranty, effectively “zero-timed.”
Cons: More costly than used engines.

New (Crate) Engines

These are brand-new engines directly from the factory (Mopar).

Service warranty Terms: A buyer must try to find a warranty that covers both parts and labor. Some service warranties are just legitimate if the engine is set up by a licensed ASE mechanic.
Consisted of Components: One should identify if the engine is “Long Block” or “Short Block.”
- Short Block: Includes the engine block, crankshaft, pistons, and connecting rods.
- Long Block: Includes the brief block plus cylinder heads, camshafts, and valvetrain.
