Default Pro 4 Diff

I recently dug the my Pro 4 out of mothballs to run the Hpi challenge this summer....the problem is the diff keeps loosing after three laps or so.......melting the outdrives. I would like to find some steel or Aluminun replacements.......I found Delrin at RCMART.......not sure if they would be any better than the stockers in there now.

If you know of a place let me know


THANKS..............

one of the guys in the forsale forum is selling delrin outdrives at cost. Why does the screw keep loosening up?

I got to looking closer this time at the gear ring...it was worn at the diff ball holes.....I ran low turn mod motors in the thing at open parking lots for fun and thought the drives where the weak point.........turns out he diff balls melted into the gear and once it loosened everything melted........

From memory, the diff screw loosening up in the Pro 4 diffs was a common problem. Most people fixed it by using the diff screw and nut from the TC4.
