Chamfered Front Upper A-arm for YD-4

This aluminium chamfered front upper A-arm is an optional scale accessory intended for the YD-4 series of 1/10 electric RC touring cars. It replaces the standard plastic upper arm with a machined aluminium piece to sharpen installation fit and increase structural rigidity.

The part is supplied as left and right pieces, and is designed to accept the existing upper arm rod end for the YD-4 layout. On-track, the upgrade helps reduce flex at the upper link, which can translate into crisper steering feedback and more consistent suspension behavior during repeated runs.

Specifications

  • Item: Chamfered front upper A-arm (left and right)
  • Material: Aluminum alloy
  • Model Number: Y4-008FUC
  • Compatibility: YD-4 chassis

Use this arm when you want a firmer front upper link with repeatable mounting geometry; it is suited for drivers tuning steering response and front suspension precision on YD-4 cars.

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.

Is this part compatible with all YD-4 variants?

It is designed for the YD-4 chassis family; verify your car uses the standard YD-4 upper arm mounting and rod end arrangement before installation.

What does chamfered mean for this A-arm?

Chamfering refers to the angled machining on edges to improve fit and reduce interference with adjacent suspension parts while keeping the arm profile slim.

Will this change shock geometry or require other parts?

The arm is a direct replacement for the YD-4 front upper arm and uses the same rod end; no additional parts are normally required but check clearance and alignment after fitting.

How does aluminium affect handling compared to plastic arms?

Aluminium increases rigidity and repeatability of the mounting point, which can lead to sharper steering response and more consistent suspension behavior under load.
