B.ZSSY 5494878RX 6.7L Cummins Turbo Actuator Calibrate Kit for Ram 2013-2018 Diesel 2500/3500/4500/5500

Overview

The B.ZSSY 5494878RX Upgrade Kit is designed for Ram trucks with the 6.7L Cummins diesel, covering 2013–2018 models in the 2500, 3500, 4500, and 5500 series. This package combines a replacement turbo actuator with a turbine calibration module to help restore precise throttle response and steady turbo behavior. Users may notice smoother operation and more consistent power delivery thanks to the integrated calibration approach.

Built to work with variable geometry turbochargers, this kit targets drivers seeking a solid, long‑lasting upgrade without resorting to more invasive engine work. While results can vary based on vehicle condition and installation quality, the combination of a new actuator and calibration module is intended to support reliable turbo performance over time.

What’s Included

• Turbocharger Actuator x 1
• Adapter Harness x 1
• Detector x 1
• Install Installation Guide x 1
• Long Screw x 2
• Short Screw x 2

Key Benefits You May Experience

• Enhanced throttle responsiveness and more predictable engine feel
• Improved turbo consistency during acceleration and load changes
• Potential reduction in intermittent turbine noises that affect driving comfort
• Durable replacement part set designed for long‑term use

Important Installation Notes

For 2018 and newer Ram models, the included instructions do not cover programming. A security bypass OBD2 cable, purchasable separately, may be needed to complete calibration and avoid the module entering calibration mode. The process typically takes only a few minutes with the bypass cable.

Installation uses the turbo actuator calibration tool and the provided guidance. Ensure the turbine gear is positioned at the leftmost limit (maximum flow) during assembly to maximize calibration chance. A careful review of the installation and calibration instructions is suggested before starting.
