Exergy E06-10250 Replacement Fuel Rail | 2004.5-2005 GM Silverado/Sierra 2500HD/3500HD 6.6L Duramax LLY

Exergy Performance is a division of Exergy Engineering and is focused on the unique needs of high-performance diesel applications. The need for this specialized attention was recognized after assisting in root cause analysis of everything from rough idle to broken engine components caused by well-meaning, but inexperienced and/or under-equipped fuel system modifiers. Given our history in the world of diesel fuel injection, we have a distinct advantage in the areas of experience, innovation, and test equipment. With our background in OE development and manufacturing, we bring a unique perspective to the high performance world. We know what various features and specifications need to be to ensure proper function, how to produce them, and how to verify they are correct. The verification process/equipment we use is very untypical of a standard diesel repair shop and allows us to look at many more system performance characteristics beyond average fuel output.
