Brena Racing CT9A (Evo 7-9) transfer case crown wheel and pinion – 16NCD12.

These crown wheel and pinion sets are running in some of the fastest Evos on the planet.

The latest version are cut and finished with a Gleason profile grinding machine, which leads to lower loads on the housing than previous versions – this means less gear deflection and less chew out in high horsepower applications.

These sets run reliably up to about 350wkw in standard OEM cast housings, and well over 550wkw in billet housings with the right setup. These sets have ran deep into the 9s here in Australia, and have seen multiple 8 second quarter mile passes in Europe.
