Ram ProMaster Accumulator 68133085AA 68226975AA

New OEM replacement accumulator.

This is a regular wear item.

Failure of unit will cause system to fail at different shifting scenarios and will trigger error codes that might not directly point to accumulator.

When diagnosing any system issue, It is recommended to always test accumulator nitrogen backpressure first to make sure it is within specification.
