Mitsubishi 4G63, 4G63T, 4G64 6 Bolt Race Series ACL STD main bearings ACL-5M1144H-STD

Main bearings Mitsubishi Std 4G63 / 4G63T / 4G64 (1983-1992) 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. Advanced technological process allows the bushing to adapt to the deformation generated at high revolutions and helps in the formation of hydrodynamic oil films. This technology, combined with the advanced geometry of the bushings, makes them ideal 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) ACL Race bearings are designed to work in the most extreme conditions and the most strained engines. Thanks to many years of experience in the production of bearing panes, each set is ideally suited to the engine. The advanced technological process allows the bearing to adjust to the deformations arising at high revs and helps in the production of hydrodynamic oil films. This technology, in combination with advanced cup geometry, makes them ideal for heavily strained engines.Most panes 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 cut) + 0.50 mm (second shaft cut) Main Bushings Mitsubishi Std 4G63 / 4G63T / 4G64 (1983-1992) ACL Race bushings are designed to operate in the most extreme conditions and the most demanding engines.
