This solenoid bracket attaches to the Passenger's side of GM LS 4 bolt throttle bodies and provides a custom mounting point for your solenoids. Each solenoid is 360 deg adjustable to allow the perfect solenoid position. This bracket was made specifically for the FAST 90mm and 102mm Cable driven throttle bodies but can fit other throttle bodies with little to no modifications. We also offer a custom braided line kit (part # 15731LK) for those using this bracket with NX Lightning solenoids and a NX LS Throttle body Plate. Note: Some vehicles require relocation of lines and/or components to provide room for the solenoids. We also offer a bracket for the Driver's side of the throttle body (part # 15730) for use with dual stage applications or on single stage systems where clearance is not available on the passenger's side.
