Sealed Power offers five basic lifter configurations:
-
Mechanical flat lifters have a hardened iron, solid tappet that requires periodic adjustment.
-
Mechanical roller lifters feature steel rollers on the tappet to reduce friction.
-
Hydraulic flat lifters have a hydraulic cylinder that utilizes engine oil to provide a quiet, maintenance-free valvetrain.
-
Hydraulic roller lifters combine technological features of hydraulic and roller lifters to reduce friction and increase fuel economy.
-
Hydraulic lash adjusters provide lash adjustment in overhead camshaft engines.
They’re compatible with virtually any engine, including those with roller-lifter valvetrains.
