Stock bolts are one-time use. These are essential for camshaft adjuster rebuilds. The set of modified ARP bolts clamp down a maximum of 132 Nm or 98 Lbs Ft of force keeping the cams secure. The Chromoly being corrosion resistant will be perfectly situated in a surplus of oil. Similar corrosion risk as the rest of the steel components within the valvetrain heads: very low to zero inside a well lubricated environment! The appeal of chromoly steel is its astoundingly high tensile and yield strength compared to its counterpart stainless steel rendering it reusable multiple times over.

These bolts were so controversial that ARP promoted it upon its release and then took it down shortly after for having the 63 Motorsports branding right on the bolt heads.
