Build Core Engine – Important Notice

This listing is for a Build Core Engine. It is not ready to install out of the box. A good, rebuildable core is required as the foundation for remanufacturing.

A core engine undergoes disassembly, machining, and rebuilding with new or remanufactured components. The final quality depends directly on the condition of your core.

Cores must be complete, free of cracks, and without severe damage. If you’re unsure about your core’s eligibility, contact our team before ordering. You can also review additional information in our Help Center.
