Engineered specifically for the low-pressure (large atmospheric) turbocharger in the factory sequential compound setup on 2008 through 2010 Ford F-250, F-350, F-450, and F-550 Super Duty trucks powered by the 6.4L Powerstroke diesel engine, the Dieselsite Wicked Wheel 2 Low-Pressure Upgrade (Part # WW642) delivers improved boost airflow, lower exhaust gas temperatures (EGTs), and eliminated compressor surge over stock cast wheels.

Extensively tested across multiple blade configurations and pitch designs, this drop-in billet upgrade installs directly into factory housings. (Note: Factory turbo applications feature reverse threading on specific shafts; do not use impact wrenches during installation).

Key Features & Benefits

• Optimized Airflow & Boost: Advanced blade profile provides faster spool-up and stronger boost output across the RPM band.
• Lower EGTs: Improves thermodynamic efficiency to help reduce exhaust gas temperatures under heavy towing and load conditions.
• Superior Surge Protection: Eliminates annoying compressor surge and aerodynamic instability.
• High-Strength Billet Build: Precision-machined from solid billet aluminum for ultimate durability compared to brittle factory cast wheels.
