For those Common Rail Cummins with moderate fueling upgrades and pushing up to around 400 horsepower, a 62mm turbo upgrade is an excellent choice to deliver superb airflow with quick spooling characteristics, and this Viper series is hard to pass up.

IMPORTANT NOTE:

• The outlet of this turbo has been machined to accept a factory style downpipe, not an HX40 style downpipe as many other aftermarket turbos will require

The VIPER PhatShaft 62 was designed to handle mild to aggressive fueling upgrades to increase overall performance. The Viper comes equipped with an extended tip 62mm forged milled compressor wheel and 360 degree thrust bearing. The Viper utilizes a 68mm turbine wheel with a modified exhaust nozzle angle, maximized wastegate ports, and enlarged wastegate chamber for full wastegate travel. Like all PhatShaft turbochargers, it is equipped with dual grooved high performance bearings and an adjustable boost elbow.
