Cummins N14 Jake Brake Assembly 1995-2000: OEM 012214

Confident Downhill Control for Cummins N14 Applications (1995–2000)

What is it?
The Cummins N14 Jake Brake Assembly, designed for engines built between 1995 and 2000 and identified by OEM part number 012214, is an integrated engine braking system component. It works by adjusting valve operation to create engine resistance, allowing the vehicle to slow naturally without relying solely on service brakes—especially useful during long descents or controlled speed situations.

Why choose this Jake Brake Assembly?
This assembly is built to align with Cummins N14 factory specifications, ensuring proper fit and seamless interaction with the engine’s valvetrain. When engine braking becomes inconsistent or ineffective, it can place additional demand on wheel brakes and reduce driver confidence. Choosing the correct OEM-matched Jake Brake Assembly helps maintain predictable braking behavior and dependable control.
