Going from 144" to 156"- Gearing?

[fat]

I have an '06 660 RMK that I put a 156" track on. What should I do with the gearing? I thought that I would just change the top gear to a 19 tooth. Is that enough?
BTW this machine has alot of motor work and runs strong, so power wise it should be OK.

that should give you the grunt you want that will make your gearing 19/41
