Product Description

Does your Heavy Duty truck have a failed Holset HE400VG Turbo Actuator? If so, we offer a remanufactured Holset HE400VG Actuator that includes the installation kit and gaskets for Cummins ISX engines. Our remanufactured actuator ships the same day, Monday through Friday. 

Optional Calibrator Tool Rental

The actuator will require calibration to complete the re-installation. We can include an optional calibration tool in the shipment of your actuator for an additional rental fee of $100. This calibration tool allows you to accomplish the entire installation process without a trip to the dealer or mechanic. Additionally, unlike other calibration procedures, our calibration tool will not require any changes to your custom tune.

Note: There will be an additional charge of $500 if the calibration tool is NOT returned to us within 15 calendar days of the receipt of this product.

  • All ball bearings are replaced with OEM bearings
  • All work is performed in-house at our facility in Greenville, SC
  • Our No-hassle 1-Year warranty covers the entire actuator

  1. The purchase of this replacement turbo actuator requires your original "core" be shipped to Circuit Board Medics after you receive the module. We do not require an up front core deposit, but a core charge must be captured if a rebuildable turbo actuator is not returned to Circuit Board Medics. If your core is not received within 15 calendar days, an additional core charge of $350 will be charged to your credit card.
  2. Your original turbo actuator must meet the following qualifications:
    • No prior repair attempts
    • No damage to the housing
    • No fire damage
    • Must be a genuine Holset actuator
