Profile: Wuxi Credible Turbochargers Co., Ltd. is a manufacturer of automotive turbochargers and their components. We are accredited with ISO 9001:2002 certification. A turbocharger is basically an air pump. Hot exhaust gases leaving the engine after combustion are routed directly to the turbine wheel side of the turbocharger to make it rotate. The turbine wheel is connected by a shaft to a compressor wheel. As the turbine wheel spins faster and faster, it causes the compressor wheel to spin quickly. The rotation of the compressor wheel pulls in ambient air and compresses it before pumping it into the engine's chambers. Our TD series turbos are precision-engineered & calibrated with VSR balancer. We also offer shaft wheel, compressor wheel, service kits, thrust collar, thrust bearing, journal bearing, ball bearing, solenoid valve, and actuator.
