BC cam bolts for the Subaru EJ engine platforms are made from ARP2000 material and feature a silver CAD plated finish to eliminate corrosion from handling. Hardened to RC 45-47, and includes plated washer (.200” thick) , the new BC cam bolts secure the cam gears permanently without the stretch common with OEM fasteners. Reduces the risk of the gear coming loose and causing severe engine damage. Works with all brands of camshafts and cam gears. The BC bolt is made to stock dimensions (2.040” under head length) with OEM thread pitch. Bolts sold as individual units.
