Mopar Performance 5184332AA Hydraulic Valve Lash Adjuster

The Mopar Performance 5184332AA is a genuine OEM hydraulic valve lash adjuster (also known as a valve lifter or tappet) that maintains proper valve clearance for both intake and exhaust valves. This hydraulic lash adjuster is a hollow cylinder with one end closed off and the other containing a piston, positioned between the camshaft and the engine valves.

Key Features:

• OEM lash adjuster engineered to meet factory hydraulic and tolerance specifications
• Maintains zero valve tolerance in your engine, eliminating the need to constantly adjust valve clearance
• Quiets the engine and prolongs its life
• Compatible with multiple Mopar engine configurations including 2.0L I4, 2.4L I4, 3.0L V6, 3.2L V6, and 3.6L V6 engines
• Genuine Mopar Performance quality with factory warranty

How It Works:

The hydraulic lash adjuster uses oil pressure and a plunger housed inside the lifter to function. When the valve is closed, oil fills the hollow part under the plunger. When the valve opens, a one-way check valve ensures the pressure is maintained.

Signs of Failure:

• Faulty hydraulic lash adjusters will produce noise when you have the engine idling at average operating temperatures
• Worn plungers and leaking check valves also indicate a need for a replacement
• When faulty, it could damage several vital components like the pushrod, valve tip, and rocker arm

This genuine Mopar part is manufactured to strict factory specifications and is the correct replacement for select 2011-2026 Chrysler, Dodge, Jeep, Ram, and Fiat models. When replacing valve lash adjusters, proper installation with a thin film of oil on bearing surfaces is recommended for optimal performance.
