The MT-009 swing shaft is a direct replacement intended for Team Losi Mini-T chassis pivot locations and is supplied to restore correct rear a-arm pivot geometry. It is a service part aimed at improving pivot alignment and handling predictability under competitive running conditions.
Functionally, the shaft provides the rotary interface between suspension arms and drivetrain components. Worn shafts introduce lateral play and binding that degrade driveline efficiency; replacing the worn shaft with MT-009 reduces misalignment and supports consistent power transfer during short-track competition.
Installation follows standard workshop practice: strip the affected arm or carrier, remove the worn shaft, fit MT-009 in the original orientation, and verify free rotation and correct alignment prior to reassembly. Conduct bench checks of wheel toe and drive engagement, and perform a short on-track evaluation to confirm setup before racing.
