Heavy Duty Truck Retrofits :

Retrofit devices, parts & installation. We do it all.

Truck Retrofit DeviceWe are your best choice for diesel bus & truck retrofit solutions. If you have a 2004 truck or older, it WILL be obsolete by the end of 2013, unless it is retrofitted to meet CARB requirements.



We can help you determine whether you need to retrofit one, two or all of your truck fleet to remain compliant. Chances are you can get away with remaining CARB compliant with as little as one truck retrofitted. (depends on fleet size, age and other factors.. which only VVG helps you determine, for free!)

We can help you no matter what you need.
