This is an optional XRAY 1.0mm Anti-Roll Bar, and is intended for use with the XRAY XB4 1/10 scale 4WD buggy. This bar can be used in the front or rear of the vehicle and is thinner/softer than the stock 1.2mm bar included with the XB4.
XRAY anti-roll bars are manufactured from special spring steel material and are used to stabilize the car. Both the front and rear bars are mounted to the differential cases and can be easily adjusted via linkages. The bars are laser engraved for easy identification and are available in different sizes for fine-tuning options.
