Roto Grip® sets the highest standard with the introduction of the Ultra Sonic. This entry performance pearl tops its class in price, performance and looks.

The power plant inside the Ultra Sonic is the unmatched X-1 core. This high RG and medium/low differential core delivers added length with constant backend motion.

Sure Grip II pearl surrounds this jewel giving it a stronger footprint on those medium to light oil patterns.
