Crower's new cam sprockets are made from premium 6061-T6 billet aluminum and incorporate a four bolt ARP fastening system to prevent the slippage found in other brands. For the ultimate tuner, Crower sprockets feature 5/16" diameter, 12 point ARP fasteners with a hardened washer to prevent galling and stripping. The lightweight design reduces unwanted harmonics which could cause valve train failure.
