ARP Conrod Bolts BMW S55 M3 M4 BEB-75/12
ARP Con Rod Bolts are an absolute necessity in highly tuned engines - although they may seem like an expense you'd rather avoid at the moment, they could prevent a very large repair bill further down the track. Standard connecting rod bolts can fail when subjected to the increased loads encountered in tuned engines working at higher than standard revs. ARP High Performance Con Rod Bolts are constructed from heat treated 8740 chrome moly steel which has a tensile strength of 200,000 psi. They are proven to be almost 5 times more reliable than standard Con Rod Bolts.
