Travel Limiting VCT
​Two reasons to use this, first it limits travel to 12 degrees that allows for longer camshaft events with no/minor modifications to piston.  The stock VCT unit has 50 degrees of travel and can/will result in piston to valve contact on start up with longer duration/larger lift camshafts, second it allows for a usable range of VCT for optimal low speed torque and high-speed power when tunned, recommend for use with OBR control system.

$225 with exchange, or $345 with no exchange.
