All our connecting rods are recognizable by the LASER "PROTOXIDE" branding if they have no logo or if they have other logos they are definitely not Protoxide connecting rods. Be wary of imitations !

These are the usual and only connecting rods we have been marketing since 2003 and we can claim "never a broken or backward one until today, who else can claim that ?

By purchasing ProtoXide steel connecting rods with ARP inverted H-bolts, you are entitled to receive all the assembly instructions, tolerances and tightening that you need, so in case of any doubts or assembly issues, one of our technicians will always be at your complete disposal to solve any kind of problems, and provide you with all the correct instructions to perform a correct assembly right along with you.
We have many technical drawings of many other connecting rods already made but not in this online catalog, for any samples of steel connecting rods not in the catalog or with different lengths please contact us by phone. Rremember that at 9000 rpm a connecting rod goes up and down 150 times in a single second !
