A Detroit 12.7 overhaul kit contains all the necessary components to rebuild your Detroit Diesel Series 60 12.7L engine. These kits typically include pistons, liners, rings, bearings, and gaskets, providing a comprehensive solution for engine restoration. Choosing the right kit can significantly extend the lifespan and improve the performance of your engine.
Why Overhaul Your Detroit 12.7?
Overhauling a Detroit 12.7 engine is a significant undertaking, but it’s often more cost-effective than replacing the entire engine.

This can lead to improved fuel efficiency, reduced emissions, and increased power output.
