Ok - so totally normal for all that play? The reflex white 64p spurs seems the loosest but the pn LSD are pretty loose as well

The Reflex spur's have very little cross section so the gear has less thickness or width than the dif balls do. You can actually make your own lightweight spurs minus the hokey LSD part with a piece of 200 grit sandpaper on a flat surface. Just sand the gears on both faces until all material other than the dif ball area has been removed. I have never found any loss of durability in the gears by doing this. If I am running anything other than a 70T I leave the gear a little thicker to absorb the torque increase.

Grant, It's hokey in the sense that the every day driver wouldn't feel the benefit or any discernible difference between a standard 64p and an LSD 64p....at least that's the way I would read and understand that.

Today I tried a slightly thicker Tamiya silver 2mm e-clip, it cleans up a lot of the slop & does not seem to inhibit smooth, consistent diff operation ..... seems like a winner

Well put Cowboy. Thanks. In truth I still run them in one class for the additional loss of rotating mass but I install it backwards so it can't lock. It has proven to be a very durable part.

I am also using the PN LSD spur gear and found that it is easy to get dust stick on diff ball and need to rebuild. The diff ball hole on this gear move outward on the spur gear and the diff disc can only cover half of diff ball. Is there any way to reduce dust from getting into the ball diff? Thanks.
