Mitsubishi Rayon has been developing premium graphite golf shafts worldwide for more than 25 years, redefining quality and high performance in the process. With a rich history tied to the Mitsubishi keiretsu, a group of companies affiliated through cross-ownership, Mitsubishi Rayon Co., LTD. (MRC) formed its own organization in 1933 primarily as a manufacturer of rayon fibers. Since that time the company's interests have diversified and expanded to include chemicals, plastics, fibers, and a variety of specialty products including composite golf shafts. Today, MRC is considered a world leader in the manufacturing acrylic and carbon fiber, with over 9,000 employees and consolidated revenues of nearly $3 billion USD globally.

Mitsubishi Rayon's Graphite Shafts, now known as MRC GOLF, has been producing golf shafts for more than 25 years. During this time MRC GOLF has grown to become the leading supplier of premium graphite golf shafts in Japan, and has now expanded its distribution to the U.S. golf market.

With many of the world's players using Mitsubishi Rayon golf shafts and an unprecedented number of Tour wins worldwide, Mitsubishi Rayon has established itself as a dominant force in the graphite shaft market.


For the player who wants the smooth and stable bend profile associated with Diamana Blue Board, but can benefit from a more stable tip-section that produces lower launch and spin characteristics.

Diamana Kai'li incorporates MDI Technology into the original Diamana Blue Board bend profile with a slightly stiffer tip and butt section. The result is a lower torque shaft that provides the same versatility as the original smooth and stable profile, while delivering slightly lower launch and spin.


For the player who desires an active bend profile, that delivers high launch, less spin and a penetrating ball flight.

Diamana 'ilima incorporates MDI Technology into a new shaft design. Diamana 'ilima features an active, low torque tip section, with a stiff mid section and moderate butt-section. The result is a shaft that dynamically promotes energy transfer throughout the swing while delivering a penetrating ball flight with low spin.


The JAVLNFX Series utilizes proprietary carbon fibers - developed exclusively by Mitsubishi Rayon - to maximize bend profile characteristics to suit players of all abilities.

The JAVLNFX Y-Series is for the player looking for the benefits of lightweight shaft technology, combined with the versatility of the JAVLNFX Series.


The Bassara UL Griffin bend profile features an elastic titanium fiber to reinforce the tip-section of this next generation lightweight performance shaft. This proprietary titanium fiber, combined with the unique Griffin bend profile helps promote more consistent, repeatable dynamic loft at impact, and increased ball speed.
