BC JZ Cam Gear Bolt ARP 2000. If you have bigger cams and/or a high engine redline, check out this upgraded cam gear bolt from Brian Crower! Custom made by ARP for Brian Crower, these are quite a bit stronger than the stock bolts. For VVTi engines only one is needed (only fits the exhaust cam on VVTi engines), for non-VVTi please purchase 2 bolts. Each bolt includes a washer. Fits 1JZ-GTE, 2JZ-GTE, and 2JZ-GE.
