I don't know what gears are stock on that revo, but in general you can go a few teeth larger on your spur to gear it down slowly. For more dramatic results, go for a smaller bell. What really matters is the gear ratio. If I were running 4:1 gears and wanted more torque, I'd try 4.25:1 or 4.5:1

thats 2.7:1 - regearing isn't going to change your torque per say, you will simply accelerate faster at the expense of top speed. If thats what you're going for, try a 40T (2.8:1) spur or a 13T (2.9:1) bell. For a more dramatic change you can try 12T bell, which is 3.1:1

If it were me, I'd get a 40T spur and a 13T bell - with that and your stock gears, it should give you a few ratios to try out.
