The Yokomo D-156-21AA aluminium rod end adapter is a finely made component intended to improve the handling of YD-2 and YD-4 chassis. Its lighter construction replaces the stock steel option to give crisper responses at the wheel.
Engineered for A-arm conversion on YD-2 and YD-4 cars, this adapter keeps the original part dimensions to ensure an easy fit. It works well with resin arms and lets you retain the standard tread width for stable set up adjustments.
Choosing aluminium reduces mass compared to steel, yielding better agility and faster steering reaction that benefits both drifting and tight precision runs. The D-156-21AA is a pragmatic upgrade for those balancing longevity and weight savings.
