Important notes:

* If you are purchasing the packs which include the Billet steel cap, please remember to leave a note about the gear ratio of your differential. There are 2 types of caps depending on the gear ratio (2.64-3.07 & 3.15-4.45), so you need to let us know which one to send you.

By replacing the existing clutches with the new ones, you will refresh your differential and restore its original performance. For improved performance and higher intensity in daily street and track usage, we recommend Stage 1 and 2 packs. To gain maximum performance, check Stage 3 and 4 packs. Not only that, but we’ll give you a LIFETIME WARRANTY on those sets!
