Main bearings STDX Nissan 1968-1974 L16E, L18E 1595-1770cc Race Series ACL ACL-5M1172HX-STD

Main bearings STDX Nissan 1968-1974 L16E, L18E 1595-1770cc Race Series 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. Advanced process 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: STDXX - 0.025 mm (looser than nominal) STDX +0.000 mm (nominal) +0.025 mm (tighter than nominal) +0.25 mm (first shaft grinding) +0.50 mm (second shaft grinding)
