The Ranger RWS-1B bubble wheel balancer offers precision and accuracy when balancing automotive and light truck wheels, even on the go. 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 make short work of any balancing task, while the hardened pivot pin and cast pivot seat provide unparalleled durability. BP#5156100
