Smeding Diesel S300 Turbo Kit for '03-'07 5.9L Cummins

The Smeding Diesel S300 Turbo Kit is a game-changer for 2003-2007 5.9L Cummins owners seeking enhanced performance and reliability. This kit features a proven S300 turbo platform, known for its robust design and exceptional durability. With the ability to handle higher boost and faster shaft speeds, the S300 is perfectly suited to meet the demands of modern diesel owners. This kit offers a cost-effective solution for upgrading your engine's performance without breaking the bank.

Unmatched Performance and Reliability

The S300 Turbo Kit comes with a comprehensive package, including a new two-piece T4 divided exhaust manifold, fresh exhaust manifold gaskets, and mounting bolts. This ensures a seamless installation process and maximizes the efficiency of your engine. The kit's fixed geometry design eliminates the risk of vanes seizing up or actuators failing, providing a longer lifespan for your turbo. Key benefits include improved performance, reduced exhaust gas temperatures (EGT), and higher boost potential, all while maintaining the factory air intake, downpipe, and intercooler piping.

Customizable Solutions for Every Application

The S300 Turbo Kit offers a range of options to suit every application, from stock fuel trucks to high-horsepower builds. Choose from cast or billet compressor wheels, with sizes ranging from 62mm to 72mm. Our billet wheels are CNC machined from solid aluminum blocks, providing quicker spool up and increased horsepower. Additionally, the kit supports higher horsepower levels (650+ HP) and can be further customized with heavy-duty or 360-degree thrust bearing upgrades. With pricing starting at just $1,700, the S300 Turbo Kit is an affordable and practical choice for upgrading your Cummins engine.
