This is the real deal: a genuine MOPAR OEM radiator coolant reservoir tank cap.
It fits a huge range of Jeep, Dodge, and Chrysler vehicles model years 1984 through 2017.

The part number is 55111074AB (also supersedes 55111074AA).

It's a direct replacement, factory-spec part.

Simple, but crucial—a bad cap can lead to coolant loss and overheating.

It's new, in MOPAR packaging, and comes with a 2-year warranty.

**Important note:** This cap might not fit every single model in that huge year range.
If you're unsure, it's always best to send your VIN to the seller to confirm fitment.
But if it fits, it's the right one.
Keep your cooling system sealed tight.
