High quality actuator

This is a great, high-quality actuator. It lacks the bracket for the boost solenoid on the 2004-2005 GP. However, it costs a fraction of the price than the actuator with the bracket, and worst case you can just ziptie the solenoid to something and it works just fine. Overall, I’d recommend this to someone needing a new m90 SC valve actuator that doesn’t cost a fortune.
