ARP Rod Bolt Kit - M52 M52TU M54B30 N20/N26 N54 N55 B46/B48 B58 S55
T. These connecting rod bolts are precision CNC-machined to ARP's exacting specifications and designed for optimum reliability and can be used on a variety of BMW engines.ARP rod bolts are thread rolled after heat treating, which gives them ten times better fatigue strength than those studs that are threaded prior to heat treatment (a very common industry practice). It costs more to do it this way, because it's tough on tooling, but the results are well worth the extra effort.ARP Pro Series rod bolts are far superior to standard OEM fasteners in terms of durability, and they're fully capable of handling the extra stress of high-combustion engines.BMW Fitments:1 SeriesE82 / E88 (08-13) > 135iE82 / E88 (08-13) > 135isE82 / E88 (08-13) > 1M (11-12)2 SeriesF22 / F23 (2014+) > 228iF22 / F23 (2014+) > 228i xDriveF22 / F23 (2014+) > 230iF22 / F23 (2014+) > 230i xDriveF22 / F23 (2014+) > M235iF22 / F23 (2014+) > M235i xDriveF22 / F23 (2014+) > M235i-RacingF22 / F2
