ARP Rod Bolt Kit - M52, M52TU, M54B30, N20/N26, N54, N55, B46, B58, S55

The ARP Rod Bolt Kit is part of the ARP Pro Series of premium-quality products. 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, including M52 (1996-1999), M52TU (1999-2000), M54B30 (2001-2006), N20/N26 (2012-2016), N54 (2007-2013), N55 (2011-2017), B46/B48 (2016+), B58 (2016+), and S55 twin turbo (2015-2021). 

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.
