ARP Rod Bolt Kit - S54 E46 M3 / Z4M (02/2003+ Build, M10 Size Bolt)


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. 

This set is also commonly used on Euro E36 M3 models (but not on US models). Please check with us if you have questions. 

ARP rod bolts are thread rolled after heat treating, which gives them about 1000% (that's 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.
