Product Overview

The rear crankshaft seal, OEM number 68078786AA, is fitted across an exceptionally wide range of Stellantis models sharing the 3.6L Pentastar V6 engine, including the Chrysler 200, 300, and Town & Country, the Dodge Challenger, and the Jeep Wrangler (JK) and Grand Cherokee (WK2), spanning the 2010-2023 production run. Since this seal spans so many closely related models across three brands, it's an exceptionally high-turnover part number worth stocking in significant volume for distributors serving Stellantis engine parts demand. Note that this part number has since been superseded by 68223854AA in the current Mopar catalog.

A worn or leaking rear crankshaft seal typically shows up as an oil leak near the transmission bellhousing, low engine oil level, or oil contamination on the clutch or flywheel. GSK Auto manufactures this seal to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is a Rear Crankshaft Seal?

Function: The rear crankshaft seal seals the point where the crankshaft exits the engine block on the transmission side, retaining engine oil while keeping contaminants out.

Working Principle: A lip seal integrated with a retainer housing maintains contact with the rotating crankshaft, creating a sealed barrier that contains engine oil while allowing the crankshaft to rotate freely as it transmits power toward the transmission.

Importance: On the widely used 3.6L Pentastar V6 platform, a properly sealed rear crankshaft seal is essential for preventing oil leaks and protecting the clutch or torque converter from oil contamination.

Common Failures & Signs: Oil leak visible near the transmission bellhousing. Low engine oil level from a slow leak. Oil contamination on the clutch disc or flywheel, in manual transmission applications. Burning oil smell from oil dripping onto hot engine or exhaust components.
