Thats what I wanted to here. This my first time posting here and I wasnt expecting this many replies this quickly. Thanks to all for posting. I have alot of questions about these things. One being I understand why the slipper clutch is in these but how do ya set one up. How much should it slip and do these things wear out very quickly. Are the differentials in these trucks an open one or are they a limited slip. Do you just run thicker lube in them to make them drive both wheels more?
