DeatschWerks Chevrolet LSA/LS9 Fuel Rails with Crossover

DeatschWerks is known for making reliable fuel system components, and these fuel rails are a solid example of that. If you're working on a Cadillac CTS from 2009 to 2013, especially one with an LSA or LS9 engine, these rails are designed to keep your fuel delivery consistent. They replace the factory rails and include a crossover line, which helps balance fuel pressure across both banks of injectors. This is important for making sure your engine runs smoothly and efficiently, particularly when you've upgraded other parts of the fuel system or are pushing the engine harder.

These rails are built from aluminum, which is lightweight and resists corrosion. The design accounts for the specific needs of the LSA and LS9 engines, ensuring a direct fit without needing major modifications. The included crossover line is a key feature, helping to equalize fuel pressure between the front and rear of the fuel rails. This means each injector gets the same fuel pressure, leading to more predictable engine performance and better tuning potential. They are a well-built option for anyone looking to upgrade their CTS's fuel system.

Keep in mind that these fuel rails are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and any specific hardware requirements.
