STD main bearings for Toyota 2A, 3A, 4A, 5A, 6A, 7A, 4AGE 1298-1397-1452-1587-1762cc ACL ACL-5M1695-STD

STD main bearings Toyota 2A, 3A, 4A, 5A, 6A, 7A, 4AGE 1298-1397-1452-1587-1762cc ACL ACL Race bearings are designed to operate in the most extreme conditions and the most demanding engines. each set is perfectly matched to the engine. The advanced technological process allows the bushing to adapt to the deformation occurring at high revolutions and helps in the formation of hydrodynamic oil films. The bushing is also available in several other dimensions: STDX -0.025 mm (looser than nominal) STD +0.000 mm (nominal) +0.025 mm (tighter than nominal) +0.25 mm (first shaft grinding) +0.50 mm (second shaft grinding)
