Industrial Injection 227439 SX-E Single Turbo Kit Cummins A/R - S300 63/68 5.9L 1.0

The Industrial Injection 227439 is a complete S300 SX-E 63/68 Single Turbo Kit designed as a direct-fit performance upgrade for the 2003–2007 5.9L Dodge Cummins diesel. This kit centers the highly regarded S300 SX-E turbocharger on a high-flow T4 exhaust manifold in a classic 2nd gen-style configuration, delivering a clean, purpose-built installation.

The stock turbocharger on the 5.9L Cummins is capable of approximately 400 rear-wheel horsepower at its efficiency limit. Upgrading to the S300 SX-E broadens the powerband, reduces exhaust gas temperatures (EGTs), and unlocks significantly more usable power — especially important for trucks already running a tune, programmer, or other performance modifications.

Kit Highlights:

• Turbo: S300 SX-E 63/68 — balances strong low-end spool with high-rpm flow capacity
• Turbine Housing: 1.0 A/R T4 — optimized for maximum top-end power and flow
• Manifold: High-flow T4 exhaust manifold, center-mount 2nd gen-style layout
• SX-E compressor wheel technology for improved adiabatic efficiency over standard SX units
• Complete kit includes all components needed for installation
• Compatible with 2003–2007 Dodge Ram 5.9L Cummins diesel engines

Whether you're building a daily driver, a heavy tow rig, or a performance-focused street truck, the Industrial Injection S300 SX-E Single Turbo Kit provides a proven, durable foundation for increased power output and long-term reliability.
