Product Description
CUMMINS 3937748 OEM ENGINE OIL DIPSTICK – RAM 5.9L (2001–2002)
If the factory oil stick on your 2001–2002 5.9L Cummins has gone missing, bent, or cracked at the handle, the Cummins 3937748 OEM engine oil dipstick is the direct replacement you want. This blade-style stick (approximately 47" overall) is calibrated to the OE oil pan and dipstick tube on second-gen Ram 2500/3500 trucks with the 5.9L ISB, so every oil check matches factory fill levels instead of a “close enough” aftermarket guess.
Because this is a genuine Cummins service part, the handle, blade profile, and stamped FULL/ADD range all match the original engineering. That means fewer surprises with aerated oil, low-level bearing wear, or overfilled crankcases, especially on hard-worked tow rigs and tuned daily drivers. Pair this dipstick with the correct Cummins tube and filter head components and lock in long-term lubrication accuracy on your 24-valve.
Key Benefits:
- OE-calibrated blade-style dipstick for 2001–2002 5.9L ISB (24-valve) Ram 2500/3500.
- Correct ~47" length and factory-style markings for accurate oil level readings.
- Genuine Cummins construction for heat, vibration, and corrosion resistance.

FAQ – CUMMINS 3937748 OIL DIPSTICK
WILL THIS DIPSTICK FIT MY 2001–2002 5.9L CUMMINS RAM?
Yes. Cummins 3937748 is the OEM engine oil dipstick for most 2001–2002 Dodge Ram 2500/3500 trucks equipped with the 5.9L ISB 24-valve (VP44) engine. Always confirm with your VIN or engine serial number (ESN) if the truck’s pan, tube, or long block has been changed.
WHAT IS THE STYLE AND LENGTH OF THIS DIPSTICK?
This is a blade-style dipstick with an overall length of roughly 47", using factory-style stamped ADD/FULL marks to match the OEM oil pan and tube combination on 2001–2002 5.9L ISB Rams.
WHICH PART NUMBERS DOES 3937748 REPLACE?
For identification purposes, Cummins 3937748 is commonly listed as superseding earlier Cummins part numbers 3946313, 3947228, and 3947553, as well as Mopar numbers 5017784AC and 5010964AB. Always reference the latest Cummins catalog and your VIN/ESN to confirm.
DO I NEED TO REPLACE THE DIPSTICK TUBE TOO?
If your existing tube is damaged, corroded, or mismatched, replacing it with the correct Cummins tube is recommended to maintain accurate readings. For later 5.9L ISB trucks, many installers pair this dipstick with the appropriate Cummins tube or upgrade to the 2003–2007 style using CUMMINS 3957070 OEM ENGINE OIL DIPSTICK TUBE – ISB 5.9L (2003–2007) when reconfiguring the system.
IS THIS A GENUINE CUMMINS PART FROM CPP DIESEL?
Yes. CPP Diesel supplies genuine Cummins 3937748 OEM engine oil dipsticks sourced through authorized distribution, so you get factory-correct materials, geometry, and markings – not a generic copy.
