AW-17220743903, GT-K4ZB5X3V
Keep your 4x4 working hard with quality transfer case assemblies and service parts for your 2019–2024 Ram Heavy Duty. CPP Diesel stocks reman units, case halves, master rebuild kits, chains, bearings/seals, encoder motors, forks, sensors, yokes, and more—curated to fit 6.7L Cummins applications.
Check the metal ID tag on the case and decode your VIN. Match shift type (electronic/manual), sensor connectors, and input/output styles against the product listing.
A stretched chain usually shows as grinding or pop/jump under load in 4WD. Encoder motor issues often cause failure to engage/disengage ranges with dash messages or blinking mode lights.
Follow the owner’s manual and each product page—many late-model units use ATF-type fluids. Fill to the correct level (not just capacity) with the truck level to prevent over/underfill.
Most replacements do not require programming, but an initialization/relearn procedure may be needed. Follow the service steps and ensure the connector/part number matches your truck.
Use the correct installer tools, verify vent function, and set preload/torque per the service manual. Replace single-use nuts/seals where specified and recheck for leaks after the first drive.
