The Ranger RWS-1B Bubble Wheel Balancer offers uncompromising sturdiness, portability and balancing accuracy for car and light truck wheels. Equipped with a self-leveling stand, the RWS-1B requires no extra leveling legs so it's ready to go anytime, anywhere. The self-aligning, spring-loaded cone and plated steel guided rods makes short work of any balancing task, while the hardened pivot pin and cast pivot seat provide unparalleled durability. Throw in the fact that the head cone is made of die-cast aluminum, and you can rest assured that this balancer is capable of handling more than its fair share of overtime, be it in the shop or onsite in the field.
