The HD-1218TH is one of the strongest standard-size servos Pololu carry. Digital electronics combined with a coreless motor, titanium-shielded aluminum gears, and two ball bearings give this servo a distinct edge over typical standard-size servos. Unlike typical hobby servos, the 1218TH has an operating voltage range of 6 V to 7.4 V. This servo works with standard RC servo pulses at frequencies up to 333 Hz. The 12″ (300 mm) lead is terminated with a standard “JR”-style connector, which is Futaba-compatible. The picture below shows an example of the hardware that might be included with this servo (hardware might vary).
The picture below shows the all-metal, titanium-shielded aluminum gear train and ball bearings that help the servo deliver such high torque.

You can find more information about this servo under the specifications tab and in its datasheet (380k pdf).
Note that, as with most hobby servos, stalling or back-driving this servo can strip its gears.
