ACL thrust bearings for Toyota 1JZ and 2JZ engines with standard crankshaft. ACL thrust bearings are used for engine rebuilds, tuning and performance builds where the axial movement of the crankshaft must be correctly controlled.
The thrust bearings control the forward and backward movement of the crankshaft in the engine block and are an important part of the engine bottom end. Correct axial clearance is important for stable crankshaft control and for reducing unnecessary load from the clutch, flywheel and other rotating components.
ACL bearings are developed for engines where better quality and higher load capacity are required than ordinary standard bearings. Improvements in material, dynamic thickness, heat transfer, oil grooves and oil distribution are some of the points that make ACL one of the leading manufacturers of engine bearings.
