This is the CRC Molded Servo Part Set and is intended for use with the CRC Gen-XL pan car. This set includes a Servo Saver brace and two Servo spacers. These molded parts are very strong and included as stock equipment with the Gen-XL. The servo saver brace 'beefs up' a Kimbrough servo saver making it stronger in the area where the ballstuds attach. The servo spacers push the servo forward for extra ackerman adjustment and also for that little extra room to get the ESC behind the servo.
