Default 12/47 Differential in Front and 13/37 in the Rear?

I ordered the complete Traxxas differential (#6789) to install in my stampede 4x4. I converted my XL-5 to brushless years ago and my rear diff needs replacing. It just occurred to me that the gears in #6789 (13/37) are different than the gears in my stock front (14/47). Do I need to have the same gearing front and back? I'm assuming yes?

Yes, the gear ratios absolutely need to match in the both diffs.
