STD main bearings Toyota 1985-1999 1E, 2E, 4EFE 999-1332cc ACL ACL-5M8392-STD

STD main bearings Toyota 1985-1999 1E, 2E, 4EFE 999-1332cc ACL ACL Race bearings are designed to work in the most extreme conditions and the most demanding engines. Thanks to many years of experience in the production of bearings, each set is perfectly matched to the engine. technology 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 heavily stressed engines. Most bushings are 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)
