4WD applications require unique solutions due to their low speed, high friction heat building properties, often due to oversized wheels and extreme downhill braking angles. Delios XP7 Command 4WD series rotors are engineered to facilitate heavy 4WD applications through the use of thermally stable, wear resistant, and stress relieved make-up of the disc and are uniquely out-gas vented to give the best clearance of water, debris and hot gasses often associated with 4WD activities. Command series is available with the durable, environmentally friendly Pro-Tekt coating or Geomet Coating.
