Calibrated Power Stealth STR Stock Replacement Turbo 04.5-07 Ram 5.9L Cummins

Are you looking to upgrade your stock Cummins turbo? Power Stealth STR Turbo is a performance-driven upgrade that delivers more air, faster response, and greater reliability without sacrificing daily drivability. Unlike many stock turbo replacements, the Stealth STR comes with no Core Charge. Designed as a direct bolt-on replacement, the STR boosts airflow from the factory 60 lbs/min to an impressive 66 lbs/min, delivering a roughly 10% increase in airflow over stock. The result? Stronger throttle response and improved efficiency. With lightning-quick spool characteristics that closely mirror the factory HE351, this turbo delivers smooth, responsive performance in daily driving while providing the added airflow needed for towing, tuning, or spirited use. If you want stock-like drivability with a noticeable bump in performance, the Stealth STR is the upgrade your Cummins has been waiting for. At the heart of the Stealth STR is a precision-engineered 60mm billet compressor wheel paired with a matched compressor cover for optimized airflow and efficiency. The billet design enhances durability and structural strength over cast alternatives while maintaining excellent balance for consistent performance under boost. Engineered as a seamless direct-fit unit, installation requires nothing more than removing the factory turbo and bolting the STR in place, no fabrication or custom tuning required for basic operation. Built to handle the demands of daily driving, towing, and performance applications alike, the STR delivers long-term reliability, rapid spool-up, and the airflow capacity needed to support both stock and mildly modified setups.
