Bring your Cyclone Touring Car to the next level with the new Pro Spec Ball Differential set from HB. Developed through intense testing world wide by our factory drivers these new differentials improve both performance and durability in one complete package.

Included in the set are our new 3mm oversized ceramic diff balls. Bigger balls mean a larger contact patch on the diff rings for smooth operation under any load. The high quality ceramic coating ensures that the diff balls will maintain there shape at any diff setting, with any motor.

Also new is our beefed up 2.6mm Titanium Nitride coated diff screw. Put through its paces by HB pilots Atsushi Hara, and Hayato Matsuzaki our new screw is designed for the ultimate in durability.

In order to accommodate the larger materials the kit also comes with a new 39t diff pulley, out-drives, thrust assembly, and diff spring made from the same proven HB materials as our Moore-Edition Cyclone and HB D4.

If you have a Cyclone tourer and are looking for a competitive edge look no further than the Pro Spec Ball Diff.
