Core Requirements

⚠️ A rebuildable core is required. Your rebuilt engine work will only begin after we receive your core. We require the engine here to begin inspection and repair. After placing your order, we’ll send you a shipping box, prepaid label, and schedule pickup. Just remove the exhaust and sensors, then ship the core — we’ll take care of the rest. Full details are available in our Help Center.

Warranty Options

Every rebuild includes a free 1-year warranty. For added peace of mind, upgrade to our 2-year no-fault warranty, which covers your engine under nearly any condition.
