    i was thinkin about pickin something like this up. i hear good things. so im thinking one of these diffs with some thicker than stock(what ever stock is) diff fluid so i get less slip and more equal spinning of the drive tires.

    Stock diff uses grease not diff fluid and it is not a sealed unit so if you try to use diff fluid it leaks out rather fast. Even the grease gets forced out of the stock diff.

    Look into the Hot Racing sealed diff. It comes with lots of great reviews. I use one and love it. Unlike the stock diff the HR diff is sealed so you can add diff fluid to get the spool feel and still be a open rear end.

    Some people sat that hr ones seep out around the screws, also i WOULD put thread lock on them, because it is metal on metal and that might help the seepage.

    not thread lock, use teflon tape on the screws, only fill the diff half full and use grease or green slime to prelube the gaskets and xrings on the out put shafts. Check out the Hot Racing sealed differential review for more info and tips and tricks.

    Start around 50,000 wt. You can then decide to go up or down in wt if you need a stiffer or looser diff. wts avail go from 1000wt all the way up to 500000 wt. You have a ton of options there. In my sealed diff(sealed stocker) I wound up liking 100,000 wt for bashing, but kept leaking out. The hr diff has been working for guys on here much better than the modified stock diff.

    I like 50k in my HR diff. I race on a very high traction hard pack clay surface. I tried 100k weight and i got to much push in the corners, the diff acted to much like a spool. So i went back to 50k and thats what i been using. I get good straight launches very little if any push around really tight corners. The amount of grip on the surface you mainly race/bash on is gonna dictate how thick oil you want to use. The thicker the oil the more it will act like a spool (locked diff).

    I love ball diffs. But unless you know how to exactly build a ball diff(alot more involved then following the instruction with the traxxas one) or running mild power the traxxas one strips easily.
