Tamiya F103, 104 & RM01 1/4 Bearing Rear Axle Height Adapter by Factory Pro O-AP0008  [FP-O-AP0008]

Rear axle height adapter for F103/F104/RM01

This Factory Pro O-AP0008 accessory is an RC-scale rear axle height adapter designed for use with Tamiya F103, F104 and RM01 on-road chassis. It interfaces with a 1/4 bearing seating to provide incremental changes to rear axle height, offering a focused way to alter rear ride height and balance without changing major suspension parts.

Compatibility is explicitly limited to the listed Tamiya chassis; confirm fit on your specific variant before installation. The part is intended for hobby and track tuning of electric on-road models and not for any real vehicle application.

Installation is straightforward for those familiar with on-road chassis maintenance: remove the rear axle support components, position the adapter at the bearing seat as required, and reassemble using existing hardware. Typical adjustments are small and should be checked on a setup stand or during slow test runs to assess handling changes.

Use this adapter as a precise tuning element to refine rear-end geometry and balance on compatible Tamiya on-road cars; make incremental changes and test before committing to a setup.
