The Primal Scream is built to be very clean down the lane with a vicious backend motion on medium to heavy oil. It features the dual-density Impulse V2 core, which has been newly engineered to provide a 2.55 RG and .050 differential. This symmetric core provides the perfect amount of length so the Whiplash Solid Reactive shell can unleash on the backend. The Primal Scream delivers outstanding entry angle and bull-dozing continuation through the pins.
