Hey Ron! I don't have the specific details for the engine on your 2021 Ram 1500 diesel so you will have to check a few things to make sure this fits. The Kat's Heaters Engine Oil Dipstick Heater # KH15200 requires dipstick openings that are 1/4" in diameter or larger, and you have to be able to submerge it in at least 5" of oil. As long as you meet these requirements you can use it on your Ram.
Do you live up north or did you decide this would be a good idea with the cold winter and storms this year?

Hey Ron, were you able to check the dipstick opening and oil depth on your Ram to see if the heater fits? Knowing what you found could help others trying to use the same heater on their diesel trucks.
