Hot Bodies Pro Spec Diff

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
