This is a replacement XRAY Extra-Hard, 2-Hole Front Suspension Arm, and is intended for use with the XRAY T3 Foam-Spec. This molded composite front lower suspension arm features 2 shock mount holes for optional settings. The inner position is used for increased steering, while the outer position is used for more stable handling. The new optimized suspension arm provides improved traction and easier handling. The extra-hard composite mixture arms have been designed for high-traction foam-tire racing and are labeled “XH" for easy identification. The specially-formulated composite material allows for a very light, durable suspension arm that can withstand the rigors of high-performance foam tire racing. Can be also used for rubber tires.
