GF 4 DRIVER

 

 

 

 

 The Ultimate in Customization
 Classic Shape, Solid Feel
 425cc Head Size

The GF-4 incorporates KZG’s Gravitational Force technology which, with 4 weight ports, gives fitters the ability to fine tune driver performance. These GF ports provide adjustability to optimize ball flight characteristics by customizing center of gravity and spin rates for improved launch conditions that result in increased carry distance.

The 425cc classic pear-shaped design has a very traditional aesthetic and a deep, solid feel that discerning players prefer. This compact design increases workability to shape shots when needed.
