I am turning my son's slash on to a mt slash it runs with the titan 12 t and its power by a 2s lipo , what gearing should be the best for it ? Currently is running the stock. 90 spur 13 pinion .. (i believe)
Also i want to give the differential a more of a posi feel so it wont get stuck climbing of the dried creek as it does now. ..any imput on this?would 300k oil be too much?. Is there a sealed differential for it?
^that stuff is also really good.

It actually lasts a pretty good while, and it doesn't really get hot since the grease prevents a lot of movement in the diff.
Are you going to put bigger tires on it? If not the stock gearing should be fine
Then you need to drop a tooth or two on the pinion. Stock is 19T, so id go with a 16T-18T. And check temps if you have a temp gun.
Stick with the 90T spur gear and get a smaller pinion gear. An 86T spur is going the wrong way on gearing.
With the titan, use the smallest pinion you can find. A slash is heavier than a pede, and a slash mt is heavier than a slash. The titan will have a hard time pushing the big truck and bigger wheels without overheating. I would go 90/12.
