We buy and sell engine cores and engine parts. We started this business in 2020 selling inspected and guaranteed engine parts from a small shop in Houston. Thanks to our wonderful customers we have been able to grow and improve. In the fall of 2021, we were able to move to a larger facility in Humble, Texas where we have been able to provide an ever-increasing inventory of top-quality engine parts with a focus on great customer service. Our goal is to provide affordable alternatives to conventional engine part replacements that people can depend on. Recycled auto parts help keep cars on the road longer with lower maintenance costs. Not only do we seek to lower the cost of maintenance to our customers but also to help lower the environmental costs associated with the manufacture of cars and car parts.
