STRC SCX10 II Aluminum Servo Mount Brackets feature a 2-piece design that keys into the c-channel chassis rail and bolts to the stock battery tray. Machined from aluminum, these mount brackets are much stronger than the stock mounts and are a must have for high torque servo applications. Additionally, they provide additional support for the battery tray, while the variety of available anodized colors will let you add a custom look to your rig. Package includes black anodized servo mount brackets.
