Build Core Engine – Important Details

This product is a Build Core Engine, not a ready-to-install motor. Because of this, we require a complete, rebuildable core to start the remanufacturing process. Your core must remain intact, free from cracks or major wear, and without missing parts.

For this reason, we recommend reviewing our Help Center before sending your core. There, you’ll find details about shipping and acceptable conditions.

Warranty Protection

Every REV6 engine comes with coverage you can trust:

• 🛠 1-Year Warranty Included – Standard protection on all builds
• 🛠 2-Year No-Fault Warranty Option – Upgrade for $450 and receive total coverage, no questions asked
