The Brian Crower adjustable cam gear is a right-exhaust cam timing component for Subaru EJ205 and EJ257 engines. It lets tuners precisely alter cam timing to support engine build tuning and valve event optimization. Supplied as a single adjustable gear, it provides a reliable way to fine-tune timing for modified EJ-series setups where right-side exhaust cam adjustment is required.
