COMPATIBILITY NOTE:

The upgrade kits with SKU starting as am-14u5_ are compatible with the 2023-2024 AM14U5 and the 2025 AM14U6 that use the new ToughBox Mini S Gearbox. For upgrade kits that that are compatible with the older 2022 AM14U5 and the 2019-2021 AM14U4 the part number will need to start with am-14u4_

The AM14U6 is the most versatile chassis for FIRST Robotics Competition teams. The chassis was named as such because there is a flavor of this AndyMark chassis for every one of you. A version of the AM14U family of chassis exists for every teams need. All of the options available through this page include the upgrade components ONLY and will not ship with a chassis.
