Connecting rods STD BMW N63, S63 V8 Race Series ACL ACL-8B1578H-STD

BMW N63, S63 V8 Race Series ACL STD bushings ACL Race ACL 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 bushings, each set is perfectly matched to the engine. The advanced technological process allows the bushing to adjust for high-speed deformation and aids 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)
