Connecting rods STDX Porsche 911, 930 3299-3600-3746cc Race Series ACL ACL-6B2473HX-STD

Connecting rods STDX Porsche 911, 930 3299-3600-3746cc 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 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 ideal 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)
