STD main bearings Toyota 1987-1994 3E, 3EE, 5EFE 1456-1497cc ACL Aluglide ACL-5M8382A-STD

STD main bearings Toyota 1987-1994 3E, 3EE, 5EFE 1456-1497cc ACL Aluglide ACL Race bearings are designed to work in the most extreme conditions and the most demanding engines. the technological process allows the bushing to adapt to the deformation occurring at high revolutions and helps in the formation of hydrodynamic oil films. This technology, combined with the advanced geometry of the bushings, makes them an ideal solution for highly stressed engines. -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)
