Cummins Front Crankshaft Seal with Wear Sleeve 89-18 Ram 5.9L/6.7L Cummins

Are you dealing with a leaking front main seal on your Cummins? The Cummins front crankshaft seal and wear sleeve kit is the right way to fix it the first time. Instead of just replacing the seal and hoping for the best, this kit restores the entire sealing surface, eliminating leaks at the source and preventing them from coming back. Whether your truck is a daily driver or a work vehicle, this is the kind of repair that protects your engine, keeps your driveway clean, and saves you from repeat tear-downs. If you’ve got oil seeping from the front of your engine, this kit gives you a complete, reliable solution.

This kit includes a high-quality front crankshaft seal and a precision-engineered wear sleeve to restore the crank’s sealing surface. The seal is made to withstand constant rotation, engine heat, and long-term exposure to oil without breaking down or losing effectiveness. The included wear sleeve is manufactured to exact tolerances, providing a smooth, durable surface for the new seal to ride on, especially critical if the original crank surface is worn or grooved. Together, these components ensure a tight, consistent seal that holds up over time, delivering long-term reliability in demanding diesel applications.
