CHASSIS CLEANING

The chassis and underbody cop the worst of every trip, packing in mud, salt and grime where you cannot easily reach. Our chassis cleaning range gets in deep, led by the Sand Assassin™ underbody pressure washer and the 360 degree Chassis Flusher Wand. Clean out the hidden build up that causes rust, then shield it for the long haul. Essential gear for any serious four wheel driver who wants their rig to last.
