8 in. Cheek 5 in. Mouth. This traditional shank has been redesigned to better suit today's performance horse. The heavy shank is a great choice for a horse that likes to feel the bit. The ball hinge prevents pinching at the lip. This unique mouthpiece will give better shoulder lift and lateral control. The control of this bit is between the hinge port and the chain mouth. It gives good stop but is kinder to the horse due to the lifesaver. This mouth has plenty of tongue relief and the loose ring gives warning to the horse for better balance. *****LIFETIME GUARANTEE*****
