Applied use of the part for many types of engines does not imply one-size-fits-all. While we maintain an ever increasing list of part numbers for a wide variety of makes, actual applications for the same type of rod can vary greatly depending on the intended use, ranging from normally-aspirated, moderate horsepower to extreme-duty high-boost exotic fuel applications. Our shelf-stock parts are designed to meet the most common performance needs. It is always recommended that either you, or perhaps your reseller, contact our technical department prior to order to assure the parts will be the correct match for your application. This is particularly important for engine programs that are designed to make 2 or more times the base power of the OEM factory engine.
