2019-2024 Cummins Stealth STR Turbocharger (CPS200183)

The HE300VG Stealth STR Turbo is an upgraded direct replacement turbocharger for 2019-2024 Ram 2500/3500 trucks with the 6.7L Cummins diesel engine. Designed for improved performance, durability, and lower EGTs, this turbo is a strong replacement option for anyone looking for more than a stock charger without requiring custom tuning to get up and running.

Built with a billet extended tip compressor wheel, custom turbine wheel, HFV High Flow Vane technology, and a ported exhaust housing, the Stealth STR provides increased airflow, better drive pressure control, and quick throttle response. It works well on stock trucks and pairs well with box tuners or custom tuning for maximum performance gains.
