The AndyMark AM14U Family Axle Nut Holder is an essential component designed to secure 3/8-16 nuts on the axles of the AM14U chassis family. This facilitates the removal of axle bolts from the chassis exterior without requiring access to the interior rails, significantly simplifying wheel changes during competitive events. Developed by CyberTooth 3940, the holder is intended for match drilling and riveting onto the chassis's inner rail, allowing for customization and compatibility with other mounted components.
