Your selection is lower than their titanium gear servos that cause problems (that's what I have) so it may not cause issues as long as you have a decent 3a minimum bec in your esc. But still, I would look into a hitec if you want something under $100 or one of the higher end $100+ servos.
You want at least 150 in/lb torque in a 4x4 of this weight.
