Is the Losi 8ight standard or metric tools? I’m having both fit with about the same amount of play. Most likely my cheap amazon tools causing this.

Should be Standard. I have been told Losi switched to metric on the 8ight X

Eight 1.0,2.0,3.0,4.0 buggys truggys rtrs are standard
.50 1/16 5/64 3/32 is the sizes you need. The diff screws in the kit are 2mm but 5/64 fits to.

The eight x and xe are now metric now.
