Main bearings 0.20 Jeep 1964-1990 232, 241, 258 ACL Aluglide + 0.010 flange ACL-7M8879A-20

Main bearings 0.20 Jeep 1964-1990 232, 241, 258 ACL Aluglide + 0.010 flange ACL Race is 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. the technological process allows the bushing to adapt to the deformation occurring at high rpm 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)
