VANQUISH H10 OPTIC Front Axle Third Member Oversize Bearing H10012A by GPM  [H10012A]

Third member upgrade overview

This aluminium third member is an RC-scale replacement part machined from 7075-T6 alloy for the front axle assembly. It replaces the factory VPS08606 piece and relocates an oversized outer bearing to improve support at the outer driveshaft location while keeping other bearing positions unchanged.

The component is CNC finished and supplied with the fasteners and bearings shown in the packing list. All accessories are pre-assembled where applicable, which shortens bench time during a typical H10 OPTIC front-end refresh. Use medium-strength threadlocker on the screws during installation to reduce the risk of fastener loosening under normal RC suspension and drivetrain loads.

The enlarged outer bearing dimension is supplied to match heavier-duty tuning setups on 1/10 scale front driveshafts, offering a more robust contact diameter without changing inner bearing placements. This part is intended for hobby RC chassis maintenance and tuning, not for full-scale applications.

Use this third member when replacing the factory front axle third member on compatible H10 OPTIC kits to restore drivetrain alignment and to gain the benefit of the larger outer bearing support in tuned front-end builds.
