The ACL Race Series 6B1395H-STD connecting rod bushes are designed for BMW N52 and N53 straight-6 engines, specifically the 2.5- and 3.0-liter cubic capacity models. This STD version is intended for mounting with crankshaft crankpins that retain their standard sizes.
The ACL Race Series range is developed for high-performance engines and applications subject to heavy loads. On BMW N52 and N53 engines, these bearings provide the interface between the connecting rods and the crankshaft journals, with precisely defined sizes to control operating clearance and maintain the oil film.
Part number 6B1395H-STD corresponds to the standard version of this ACL product family. It is designed for crankshaft journals with a diameter between 49.973 and 49.993 mm, and a connecting rod journal diameter between 53.600 and 53.616 mm.
ACL also offers this product family in various sizes. The STD version should therefore be selected after metrological inspection of the crankshaft and verification of the oil clearance. The choice of bearing size depends on the actual sizes measured during engine assembly.
These bearings are suitable for BMW N52 and N53 engines used in various BMW models equipped with straight engines. Part number 6B1395H-STD has a maximum thickness at the top of 1.793 mm and a maximum width of 17.55 mm.
Before mounting, it is recommended to carefully inspect the crankshaft journals, connecting rod sockets, and oil clearance to confirm that the STD dimension matches the engine’s configuration.
