Help each valve follow its camshaft lobe with the Sealed Power engine valve lifter AT-872, an application-specific valvetrain component made for technicians and engine builders who depend on their parts. It fits many vehicles, among them the 1967-1969 Ford Mustang, 1954-1955 Ford F-250 and 1983-1985 Ford Ranger. See the "Vehicles it fits" section for the full list and engine details.
A valve lifter rides on the camshaft and passes each lobe's lift into the valvetrain, so the valves open and close in time with the engine. Sealed Power application-specific components are designed to help restore engine performance and to help get the job done right the first time.
- Exacting tolerances: Held to tight tolerances for the listed applications.
- Leading-edge materials: Sealed Power builds the lifter with leading-edge materials.
- State-of-the-art manufacturing: Produced with state-of-the-art manufacturing processes.
- OEM specifications: Sealed Power specifies it to OEM specifications or better.
Signs a lifter may need replacing include a persistent ticking or tapping from the valvetrain, rough running or a misfire. These symptoms can have other causes, so diagnose the valvetrain before replacing parts. Consult the vehicle service information for the installation procedure and for whether other valvetrain parts should be replaced at the same time.
