Engines Built With Unrivaled Quality

GM's engineering expertise, attention to detail, and processes all come into play when building quality engines. GM's new and remanufactured engines offer you greater assurance that they're a mirror image of the original engine, not products of reverse engineering or mere approximations of original quality and specifications.


  • Designed and tested specifically for GM vehicles
  • Validated for consistent high-quality standards
  • Past-model engines built with current-model technology
  • Next- or same-day delivery available through your GM dealer
