6.6L Duramax LGH

 

 

 

 

 

 

The LGH is a detuned version of the LML Duramax designed specifically for chassic cab & box-delete vehicles (RPO ZW9). Since these vehicles are sold as "incomplete", special emissions requirements are applied and, therefore, the LGH has a few different features than the LML. These differences include a revised turbocharger, detuned motor, higher capacity SCR system, and larger EGR cooler.
