The Yokomo Y2-008RAA Adjustable Aluminum Rear Suspension Arm is designed for YD-2 and YD-4 chassis to increase rear-end stiffness and improve handling predictability. Its adjustable layout helps you tune track width to suit different bodies and tyre choices.
Produced with Yokomo precision, the arm beefs up the rear structure so the car responds more consistently when under lateral stress. That stability makes it easier to carry speed and choose line when drifting competitively or at the club.
Includes 0.5mm, 1.0mm and 2.0mm spacers allowing adjustments from -2.0mm to +1.5mm per side compared to stock, adjustable in 0.5mm steps. If you need larger offsets, adding shims and fitting longer dogbones can extend the range to about 6 to 7mm per side.
The design lets you insert or remove spacers without taking the arm off the chassis, so you can perform rapid setup tweaks between runs. That convenience helps when adapting to changing track grip or tyre wear.
