JumboMax launches 15-inch JMX UltraLong grip: a third hand position for distance control

JumboMax put the JMX UltraLong on sale on October 20, 2026. The unusual specification is its 15-inch (38.1 cm) grip length. Rather than promising automatic extra distance, the design creates a third practical hand position, inviting golfers to use grip position as another way to manage club delivery.

What's different?

The company's official product page lists a firm Tour Series texture, a twist-resistant StabilityCore, and a lightweight construction. JumboMax says the added length causes little or no change in swing weight. Crucially, it also says the UltraLong is not a counterbalanced grip—a meaningful distinction from products deliberately designed to shift the club's balance toward the hands.

The premise is straightforward: hold the club high, around the middle, or farther down without running off the grip and onto the bare shaft. The lower option is particularly relevant to wedges and short irons when a golfer wants a controlled partial shot. It may also appeal when the ball sits above the feet or a shot must travel beneath tree branches. None of those situations is unique to this grip; the point is to provide additional usable surface.

Verified specifications

Length: 15 inches. Sizes: Standard Jumbo (+1/8 inch), Medium (+5/16 inch), and X-Large (+3/8 inch). Colour: black and white. US price: $18.99 per grip on JumboMax's official store. Online retail start: October 20, 2026. The manufacturer says it can be installed on clubs from driver to lob wedge; fitting remains important.

What the claims do—and do not—prove

Choking down on a club is an established technique. A shorter effective lever can change contact quality, perceived control, tempo and delivered speed, potentially affecting launch and carry. But three grip locations do not guarantee three precisely repeatable yardages. Club selection, shaft length, tempo, strike location and the golfer's own motion all matter.

JumboMax illustrates its concept using three wedges and three hand positions to suggest nine ball-flight and distance possibilities. That's a useful practice framework, not evidence of nine independently measured outcomes. Likewise, the official page does not provide third-party comparative testing showing measurable gains in speed or dispersion for the general golfing population. Its swing-weight statement should be treated as the manufacturer's design expectation, not an independent fitting result.

A practical way to evaluate it

Before regripping an entire set, test the UltraLong on one familiar club. Hit comparable groups from the upper, middle and lower positions, and compare them with your current grip. Record carry distance, start direction, dispersion, strike consistency and whether the head still feels predictable. Keep the ball and shaft unchanged so that grip geometry is the main variable.

Thickness and firmness matter as much as length. Some hands may welcome the larger, stable surface; others could experience tension or reduced touch. If a lower hand position improves repeatability, it is worth testing further. If it simply changes the feel without helping contact, the extra length offers little advantage.

The verdict

JMX UltraLong is a genuine equipment-design experiment: it turns gripping down into an intentionally supported part of a club's handle. It should not be presented as a universal distance booster. Its most plausible value lies in structured short-game distance control and the flexibility to adjust hand position without running out of grip.
