Build Core Engine – What to Expect
This is a Build Core Engine, not an out-of-the-box ready-to-install unit. A solid, rebuildable core is required before shipping. During the remanufacturing process, your engine is completely torn down, cleaned, machined, and rebuilt using premium new and refurbished components. If you’re unsure about core requirements, visit our Help Center or reach out to our team for guidance.
