Players Distance Driver

Epon is the house brand of Endo Manufacturing, the Niigata forging house that has quietly built clubheads for some of the biggest names in golf. When Endo puts its own name on something, club nerds pay attention. The AF-155i is the company's full-size 460cc driver, and it held an odd distinction: one of the very few Japanese boutique drivers you could actually adjust.

That matters more than it sounds. In 2019, almost every JDM head was glued, period. If you wanted a different shaft or a tweaked face angle, you were booking time with a club builder. The AF-155i kept the premium Japanese build and added an adjustable hosel, so you can swap shafts in your garage like you would with any mainstream driver.

None of that would matter if the head were ordinary. It isn't. The face is forged titanium rather than stamped, the crown is carbon, and the whole thing is finished to a standard mass-market drivers don't attempt. You pay for that. Whether it's worth it depends on how much you value feel, because raw distance is not where this club separates itself.

• You want Japanese forged construction without giving up a full 460cc head or the ability to adjust it.
• Shaft tinkerers, since the .335 sleeve makes it easy to test premium aftermarket shafts without a trip to a builder.
• Players who put real weight on impact feel and build quality, and can live with boutique pricing to get it.

Frequently Asked Questions

Is the Epon AF-155i adjustable?

Yes. The hosel adjusts loft, lie, and face angle, and the head accepts standard .335 tip shafts through Epon's sleeve adapter. That was rare for a Japanese boutique driver in 2019, and it's a big part of why the 155i exists alongside Epon's glued models.

Who makes Epon drivers?

Epon is the in-house brand of Endo Manufacturing in Niigata, Japan. Endo has forged clubheads for major OEMs for decades, and Epon is where the factory sells its own designs under its own name. The AF-155i comes off that same production line, minus another company's logo and markup.

What shafts fit the Epon AF-155i?

Anything with a .335 tip, which covers nearly every aftermarket driver shaft. Used examples commonly show up with premium Japanese shafts already installed, things like the Mitsubishi Tensei line or Fujikura Speeder Evolution. Extra sleeves are sold separately if you want to rotate between setups.

How forgiving is the AF-155i?

More than you'd guess from the brand. The variable-thickness forged face holds ball speed on off-center strikes, and the carbon crown lets weight sit low and deep for stability. It's still a fairly neutral head, though. If you fight a big slice, a draw-biased mainstream driver will help you more than this will.

Why is the Epon AF-155i so expensive?

Low volume and where it's made. Endo forges the face, builds the head in Japan, and sells mostly through fitters rather than big-box shops. You're paying for manufacturing quality and feel, not for a ball speed number a launch monitor will prove. Buying used softens the price a lot, and these heads hold up well.
