2.6mm Titanium Coated Diff Screw/3mm Ceramic Diff Balls

The all-new Pro Spec Ball Diff Set is what all the top Hot Bodies Cyclone racers are using to achieve impressive race wins and keep at the top of their game! Hot Bodies team members like Andy Moore, Atsushi Hara and Ronald Volker depend on continuous racing development and the toughest components, and the Pro Spec Ball Diff Set is designed to never let them down!
This new Pro Spec diff features several new improvements to make the diff last longer under extreme racing conditions:
39-tooth pulley is a direct replacement for the existing ball diff pulley, and features wider spacing for the diff balls for less stress and wear on the diff rings

Ceramic diff balls (#67722) are extra-smooth and super long-lasting, able to go longer between rebuilds
Cup joints are made from machined POM lightweight space-age plastic for rocketlike acceleration
Thicker and stronger titanium nitride-coated diff screw and nut will outlast the standard diff screw
Internal ball bearings, D-cut rings, spacers, diff and thrust bearing grease are all included, making this a complete ready-to-go diff set, ready to drop into your Cyclone

Optional aluminium cup joints are available
