What are your shipping and core return timelines?

We require your vehicle identification number before finalizing any order. Our database cross-references your VIN with original factory build sheets to match the exact engine code and transmission specs.

Every rebuilt engine is hooked to an active dynamometer to monitor oil pressure, thermal behavior, and compression across all cylinders. We do not ship any unit without a verified dyno-test report.

Our zero-hassle nationwide warranty covers both parts and freight. In the rare event of a component failure, we dispatch a replacement unit directly to your mechanic and cover the return shipping costs.

Units are shipped freight-ready within forty-eight hours of order validation. We provide a pre-paid freight bill and schedule the carrier to collect your old core once the replacement is installed.
