FAQ
Will this part fit my truck?
This seal fits many 2007.5–2025 Ram trucks equipped with the 6.7L Cummins engine. Always verify fitment using your engine serial number before ordering.
Is this a genuine Cummins seal?
Yes. Cummins 4931561 is a genuine OEM front crankshaft seal manufactured to Cummins specifications.
What does the front crankshaft seal do?
The front crankshaft seal prevents engine oil from leaking where the crankshaft exits the front gear housing and rotates through the front engine cover.
What are the signs of a failing front crankshaft seal?
Common symptoms include oil seepage around the harmonic balancer, oil accumulation on the front of the engine, or visible oil leaks near the front cover.
Should I replace the seal during front engine service?
Yes. Replacing the front crankshaft seal during front cover, timing, or harmonic balancer service can help prevent future oil leaks and reduce labor costs later.
Do I need any related parts?
