Fitment – Ram 6.7L Cummins Applications
This dipstick targets late-model 6.7L ISB applications that use the cable-style dipstick:

Installation & Usage Notes
- Inspect the existing dipstick tube for damage, kinks, or misalignment before installing the new dipstick.
- Lightly lubricate the cable with clean engine oil for smoother insertion and removal.
- Seat the dipstick fully against the tube stop every time you check oil level.
- On engines with non-stock pans or tubes, oil marks may no longer be accurate – verify dipstick calibration any time components are changed.
- For the most accurate reading, check oil level with the truck on level ground, engine at operating temperature, and after allowing a few minutes for drain-back.

Frequently Asked Questions
This dipstick is intended for 2007.5–2024 Ram 6.7L Cummins applications that use the cable-style dipstick. The safest way to confirm fitment is by checking your VIN or engine ESN against Cummins/Ram service information or existing part labels on the original dipstick and tube.
How do I correctly check oil level with this dipstick?
Bring the engine up to operating temperature, park on level ground, and shut the engine off. Wait a few minutes for the oil to drain back to the pan. Pull the dipstick, wipe it clean, reinsert it fully until it seats on the stop, then remove and read the level. Adjust oil quantity to bring the reading to the FULL mark without overfilling.
What if my truck has an aftermarket oil pan or dipstick tube?
Aftermarket or swapped pans and tubes can change oil level readings even with the correct OEM dipstick. If any oil system components have been changed from stock, confirm capacity and dipstick calibration during the next oil change and mark the correct FULL level as needed.
Is this a genuine Cummins part or an aftermarket reproduction?
This listing is for a genuine Cummins OEM 4938970 dipstick, sourced through CPP Diesel. It is not an aftermarket or “will-fit” copy, and is manufactured to Cummins specifications for material, length, and oil level markings.
When should I replace my original 6.7L dipstick?
Replace the dipstick if the handle is broken, the cable is kinked or frayed, the markings are unreadable, or you suspect it’s been bent or modified. Any damage that prevents smooth movement or accurate readings is a good reason to install a new Cummins 4938970 dipstick.
