HPI Bullet 3.0 Precision CVD Swing Shaft SBMT283 Steel #45 by GPM  [SBMT283]

Precision-engineered steel CVD swing shaft for HPI Bullet 3.0

The SBMT283 front and rear CVD swing shaft is CNC-ready replacement hardware manufactured from steel #45 and intended for HPI Bullet 3.0 MT and ST drivetrains. Designed to reduce material fatigue and limit flex, this component supports repeatable driveline geometry under sustained off-road loads.

Installers should verify CVD bore tolerances and retaining method prior to assembly to ensure correct seating. From a tuning perspective, the increased torsional stiffness of a steel #45 shaft changes load transfer and pedal feedback, so technicians should re-evaluate differential and throttle settings when fitting this part.

Specify the SBMT283 for a durable, direct-fit steel solution at the front and rear CVD locations on HPI Bullet 3.0 MT and ST and update driveline setup to accommodate higher stiffness.
