Heavy duty spur gear for pan cars and F1's that use 1/8" diff balls.

All machined delrin gear for ultimate roundness and flatness and much stronger and longer lasting than 64 pitch gears.

Designed with maximum hole cuts allowing the use of extra 1/8" diff balls. This allows the diff and thrust to be less tight, more free and more durable as the extra balls grips the diff rings with a less tight nut setting.

Typically we us the outer row of holes for the diff balls and the inner row of holes for mounting to the Exotek spool but you could use all of the holes for diff balls if you wish.

1/8" diff balls required- sold separately
