Dual brushless and a spool.

[JOHNNYMAXXIMA]

I am running stock diffs with a spool in the rear. Do you think that I would be able to get away with running stock gears but with the maximizer cups and aluminum case? As far as my suspension goes, I cant remember the name of the shocks that I have, (bought them on e-bay) but here is a pic of them with RPM a-arms, carbonfiber/aluminum shock tower and every thing else stock.
