Default Highest torque servo

What is the highest torgue metal gear servo available? I need at least 450 in/oz of torque, more would be better as i'm attempting a new idea for chassis mounted servos that will eliminate any bump steer.

Hi-tech 7980, 611 oz/in at 7.4 volts. People say you can hear how strong the motor is while I'm driving.

+1 for the 7980. i only have 6 volts going to it in my xr10 cause i didnt feel like running my bec straight to the servo but i still have 500 oz/in! and i havent found a spot where i wanted more. the only thing is that im trying to be careful not to rip everything else apart, just be careful with that monster

Wow, that means the servo gearbox could lift me off the ground with a 1½" horn or with a 3" wheel and continuous rotation. That's insane.

OK, someone's gotta try it now. Who's going to step up to the challenge.....?

While the 7980 is the top servo now for crawlers, it is "slighty" bigger. The 7950 at 7.4V puts out 486oz and is standard size. It is way enough servo for your needs. For the price I got mine tho, I went for the extreme over kill 7980. You need to make or modify a servo mount to fit it's 2mm wider case.

But it takes 1.76 seconds to swing 60*, I think that is a bit slow for a steering servo.
