K2 Revision A to B Upgrade

The mod kits listed below will upgrade an existing, BUILT, Revision A (or Field Test Rev. XC) K2 to one equivalent to Revision B. (The revision number refers to the PC board revision.)

We recommend that you download the K2 A to B Upgrade Instructions to review all of the changes before deciding which mod kits to purchase, as some of them are optional, and you may have installed some of them previously.

NOTE: If you have an UNBUILT Revision A K2 (s/n less than 3000) and wish to build it with new Rev B PC Boards, parts and manual, do not order the mod kits listed here. They only apply to existing Rev A K2s.
