Adjustable RB twin cam gear lock tool to suit R33 RB25 and R34 NEO RB25. May fit other twin cam RB's but has not been tested yet. Tested with factory inlet cam gear, factory exhaust cam gear and HKS adjustable exhaust cam gear.
RB25's with VCT inlet cam gears are adjustable from behind and don't always sync with exhaust cam gears. Sometimes it's necessary to adjust the inlet cam gear for RB25/30 conversions. This tool accommodates for these adjustments.
