This is a replacement XRAY XB2 Rear Left Composite Disengaged Suspension Arm (Hard).
Rear lower LEFT suspension arm with redesigned geometry for improved consistency and handling. Special design of the arm allows to move arm more frontwards that moves the weight into the rear of the car. The rear upright position in the arm is moved forward with an extensive range of wheelbase adjustment.
Made from HARD super-tough composite, this suspension arm is a perfect balance between reliability and performance; rigid enough for responsive feel and extreme durability.
