The RHF55V Turbocharger 8981479061 is a precision-engineered forced induction unit manufactured to OEM standards for heavy-duty Isuzu truck applications. Designed specifically for medium-duty trucks — including Isuzu NPR-HD, NQR, and NRR chassis — this turbocharger delivers reliable boost performance and improved engine breathing under load.
Compatible with Isuzu 4HK1-TCN and 4HK1-TCS diesel engines, the RHF55V turbocharger efficiently recovers exhaust energy to force additional air into the combustion chamber. This process increases torque output, enhances throttle response, and supports better fuel efficiency. Built with a precision-balanced turbine and compressor, robust housings, and a responsive vane actuator, this turbocharger is engineered for demanding commercial duty cycles.
Common issues with worn or failing turbochargers — including loss of power, heavy smoke, poor acceleration, and elevated exhaust temperatures — can be effectively resolved by installing this RHF55V turbocharger 8981479061. It is ideal for truck fleet maintenance, diesel repair facilities, preventive maintenance, or restoring performance after turbo wear.
Complete OEM-quality construction ensures long service life and compatibility with factory engine and exhaust configurations, with no modifications required for installation.
