Tuned stiff upper arm for R12 and GT

This hard upper A-arm is an RC-scale accessory designed for Yokomo R12 and GT family cars. The component is molded from a stiffer resin than typical stock parts, which reduces play in the upper arm during lateral load and helps stabilise the suspension through cornering. The part is intended as a tuning option to tighten front-end feel and reduce unpredictable arm motion at speed.

Installation is straightforward for users familiar with standard A-arm servicing: check mating surfaces, confirm ball joint and hinge-pin clearance, and verify symmetric fit left to right. This item affects chassis behaviour by stiffening the upper link, so use it when you want crisper turn-in and a firmer front-end response without changing geometry.

Remark :

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.

How will a harder upper arm change handling?

A firmer upper arm limits flex under side load, producing a more predictable turn-in and reducing suspension wobble when negotiating corners.

Do I need special hardware to fit this part?

No additional parts are normally required. Still, inspect your existing hinge pins and ball studs for wear and correct clearance before installing to ensure a snug, safe fit.

Will it alter suspension geometry?

This is a like-for-like replacement that stiffens the link rather than changing mounting points. Always recheck wheel alignment after installation to confirm settings.
