Looking at the popular Savox brand:
Savox - Servo - SV-1260MG - Digital - High Voltage - Coreless Motor - Metal Gear » Coreless Motor » Servos » SAVOX-SERVO.COM
But that is something you also could have found by just visiting some websites and reading the specs. I know, letting others do the job is much easier.
But really, do you need such a fast servo on a big heavy truggy? When you lower the specs on the speed to 0.1 sec at 60 degrees you will find many (affordable) options.
