Hard upper A-arm mount overview

This is an RC-scale hard upper A-arm mount designed for the R12/GT500 platform, supplied under the Yokomo YOKR12-09G part code. The mount replaces the standard upper arm mount to provide a firmer pivot point aimed at changing suspension response without altering arm length or basic geometry.

Fitment is specific to the R12 and GT500 chassis lines noted in the product name. The piece is intended as a direct replacement part and is used where drivers seek a crisper roll response or more consistent camber control during cornering at 1/12 scale club and track sessions.

Installation requires removing the stock upper arm mount and securing the replacement to existing suspension towers and linkages on the R12/GT500 chassis. Because it modifies the pivot stiffness, expect changes in transient behaviour; use incremental testing to assess handling trade-offs during setup.

Specifications

  • Item: Hard Upper A-Arm Mount
  • Material: Not specified
  • Model Number: YOKR12-09G
  • Compatibility: R12, GT500

Compatibility

  • R12
  • GT500

As an RC-scale aftermarket option, this mount is a straightforward way to alter suspension stiffness characteristics on R12/GT500 cars; evaluate changes on track and pair with corresponding damper and swaybar adjustments.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this mount fit without modifying the chassis?

It is designed as a direct replacement for the R12/GT500 upper arm mount, so no chassis modification should be required for standard installations.

What handling changes should I expect?

The harder mount tends to reduce compliance at the pivot, producing crisper transient response and more consistent camber under load; test incrementally to balance grip and rotation.

Is any special maintenance required?

Inspect mounting screws and mating surfaces for wear or loosening after initial track sessions and periodically thereafter, as with any suspension component.

Can I use this mount with other aftermarket upper arms?

Compatibility depends on the arm and tower geometry; it is guaranteed for R12/GT500 original-spec arms, but verify fit if combining with third-party components.
