Boasting the highest differential of any weight block in our lineup, RAD4 stems from the original Radial Accelerating Disc technology produced with the original X-Factor. Having been aggressively engineered over time, the amount of flare potential and backend hook is unprecedented and has attributed to the success of all Code balls. The marriage of this weight block and our trademark R2S Pearl coverstock results in a beautiful display of effortless skid through the heads and crisp cutting downlane motion.
R2S Pearl Coverstock
R2S is synonymous with some of the most successful balls in recent history like the Hy-Road, Frantic, and the IQ Tour. It is renowned for clearing the front part of the lane with an unprecedented movement on the backend. The consistency of this shell through the heads is something to be marveled at.
RAD4 Core

Radial Accelerating Disk technology dates back several generations with hints of it that can be found in the RAD4 Core. It features an extremely dense modified disc shape that generates substantial torque. So much torque, it reigns supreme at the top of the Premier line with a differential higher than any other weightblock in its class.
