FAQ
WILL THIS DIPSTICK FIT MY 1994–1995 5.9L 12-VALVE RAM?
Yes. Cummins 3928740 is the OEM engine oil dipstick commonly cataloged for 1994–1995 Dodge Ram 2500/3500 trucks with the 5.9L 12-valve Cummins. Always confirm by VIN/ESN and make sure you have the correct OEM dipstick tube installed.
WHAT IF MY TRUCK IS A DIFFERENT YEAR 12-VALVE?
Earlier 12-valve trucks (1989–1993) and later 12-valve years (1996–1998) often use different dipstick part numbers. For example, Cummins 3923128 is the matched OEM dipstick for many 1996–1998 Ram 5.9L 12-valve applications. Always match the stick to the correct tube and year range.
DO I NEED TO REPLACE THE DIPSTICK TUBE OR CLIP AT THE SAME TIME?
It’s a good idea to inspect the tube and hardware. Rusted, kinked, or loose tubes can cause false readings. CPP Diesel stocks the matching Cummins 3905801 oil gauge tube, 3905802 tube end, and 3923016 tube clip so you can refresh the entire assembly at once.
IS THIS A GENUINE CUMMINS PART OR AFTERMARKET?
This is a genuine Cummins 3928740 service part sourced through CPP Diesel – not a universal or off-brand replacement. You get OEM markings, correct length, and proper handle design for a clean factory look.
HOW DO I VERIFY I HAVE THE CORRECT LENGTH DIPSTICK?
When possible, compare this stick to your original by part number and by measuring from the stopper to the tip. Verify that it seats fully into a correct OEM tube and that the FULL mark aligns with known-good oil level. If you’ve changed pans, tubes, or blocks, matching by ESN and factory service information is strongly recommended.
