We do our best to import the highest quality engines, transmissions, and parts from Japan and thankfully our great reviews prove this.
All of our engines, transmissions, and parts come from donor vehicles that MUST have 60K miles or less. If they pass inspection including compression testing, they are then removed from their original vehicle and imported to us. They are then ready to be shipped out to you.
If there is an issue with the item you receive, the item can be returned for an exchange and/or refund (we reserve this right).
We are proud to offer the strongest and clearest warranty and return policy in the entire industry.
In the event that an item (engine, transmission, etc.) has bad compression, dead cylinder(s), head gasket problems, or any other terminal issues, we cover shipping to pick the item up and give you the option of receiving a replacement item or a full refund.
The success rate with our engines and transmissions is over 99%+, but rest assured that you are covered as if you were family. In fact, when you work with this, you are family.
