The Kyosho LAZER ZX-5 Aluminum Battery Post Set by 3Racing ZX5-26/BU is produced to tight tolerances to ensure repeatable battery placement and minimise play under load. These aluminium posts are a direct upgrade over moulded items, offering improved mechanical coupling between the battery and chassis during competitive driving.
Aluminium is selected here for its strength to weight and resistance to fatigue. In a racing context, the stiffer mount reduces micro movement that can translate to inconsistent handling and variable electrical contact under high g loads.
Install the posts with correct torque values and verify alignment with the battery pack. For race prep, use medium strength threadlocker on fasteners and schedule a quick hardware check between heats to confirm retention and electrical integrity.
