    I know locking the diff's occurs a lot more often in rock cralwing. But my questions are what is the advantages of them? is the only disadvantage to them that you turning radius is decreased? and is there a way to lock them up without buying anything? thanks

    A: you can lock them.
    B: dont!

    You will snap axles left and right because the tire on the outside of the turn travels farther thus turning the dogbone more times than the tire on the inside of the turn. When you have the Diff locked something has to give. Most of the time it is tire slippage. But the rest is broken parts.

    If you dont care then mix up some JB weld and smush it into the diff carrier bolt on the ring gear and viola. You have posi, crude but effective. Works actually pretty good in RWD Stad's when on dirt, only.

    ok, i thought the only down fall of locking them up is loosing turning radius, but I see what your saying. Maybe I'll try it on one of my old radio shack trucks...it cant hurt to break one of those right?:D Thanks

    well you probably wont find much damage with an electric truck. my evader runs fine with the locked diff but i know with nitro trucks that put out a lot of power it can kill the dogbones/axles
