Main bearings 0.01 Ford 1962-1998 255, 289, 302 V8 ACL ACL-5M590P-01

Main bearings 0.01 Ford 1962-1998 255, 289, 302 V8 ACL ACL Race bearings are designed to work in the most extreme conditions and the most demanding engines. The bushing adjusts 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 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)
