| Axial open diffs
Hey all, I have a newb question. Is there an open diff kit for axial axles? Does anyone make one or has someone figured out a way. I planning a scale build using the 70 ford f100. Most farm trucks I know of do not have locked diffs. Maybe a posi tac in the rear, but front an rear locked diffs ...no. I want the fun of wheeling an old beater farm truck, open diff 4wd FTW!!! Let me know? |

The stock wheely king diff is open and it drops right in the axial housing, I have it in my Cherokee. It's fun for trails and also is easier on your drive train in most situations.

Good for you! I did this when I first got my SCX-10 I ran the rear end locked and left the front open.. Makes for a challenging time and what was once easy now takes the right touch of throttle and timing. I haven't run open diffs front and rear at the same time but someday I will, I have all the spare parts to make it happen. Good luck |

the ax-10 rock racer/crawler came with an open or locked option. I have the open set in a ziplock. will see if i can find the axial part#. might be a good place to start looking.

thanks to everyone for helping out. In my opinion open diffs really put the scale back into it. I mean how many "street rigs/class one rigs" run locked diffs in 1:1? Almost none, not none, but almost none. Most run limited slips, or arb style remote locking diffs. Now take our street class/ Class 1 rigs. How much more scale would the crawling be if you had limited slip, or remote locking diff? It would bring that class to a whole new level of scale crawling. Obviously the class 2 and 3 rigs would be fully locked! |

Will an axial diff hold in diff oil?

| No. I tried running 100,000wt diff oil in my open front diff once upon a time for some low tech limited slip action but it didn't last more than about a month. it leaks out past the outputs.. I don't know of maybe a couple strategically placed o-rings or something might help but I never fooled with it after that.
