Upgrade Your Drift Chassis with Yokomo D-156-21AA

The Yokomo D-156-21AA Aluminum Rod End Adapter is a precision machined part designed to raise handling response on YD-2 and YD-4 platforms. Made from lightweight aluminum, it replaces the factory steel piece to reduce rotating mass and sharpen steering input.

Fitment and Tuning Notes

Built for A-arm conversions on the YD-2 and YD-4 series, this adapter matches the kit dimensions for a direct swap. It pairs well with resin arms and still allows you to set the standard tread width, making it useful for hobbyists who fine tune suspension geometry.

Why Use Aluminum Here?

The lower weight of aluminum versus steel improves agility and responsiveness, which benefits both club racing and pinpoint driving sessions. The Yokomo D-156-21AA strikes a balance between durability and reduced mass for better on-track feedback.
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 fit other brands or just Yokomo YD-2/YD-4?

It is made for the YD-2 and YD-4 geometry, but it can fit other cars that share the same mounting dimensions. Check your arm spacing and thread sizes before swapping.

How difficult is installation for a typical builder?

Installation is straightforward since the adapter keeps the original dimensions. Basic hand tools and careful alignment when installing resin arms are usually all you need.

Will switching to aluminum change suspension geometry?

The part preserves the stock geometry, so toe and camber settings stay the same. The main change is reduced weight which improves steering feel and transient response.
