XRAY have introduced medium hardness chassis side guards for the XB4. These optional medium-hardness side guards are softer than the hard side guards, and are a great tuning part for chassis flex adjustment. The side guards were redesigned to allow the motor to be positioned as low as possible on the chassis to improve cornering speed and stability.
These medium-hardness side guards make the chassis more flexible and are recommended for very-low traction tracks. Perfect fitment on the chassis seals against dirt, and provides protection from side impacts.
