  • Cons: The most pricey option; might surpass the total market price of an older truck.

Remanufactured Engines

A remanufactured engine is an utilized engine that has been totally disassembled, cleaned, and inspected. Any worn parts are replaced with new parts, and the engine is machined to satisfy original equipment manufacturer (OEM) specifications.

  • Pros: Often equivalent from new performance-wise, normally includes a multi-year warranty, more inexpensive than new.
