Max Game Improvement Driver

The Nike SQ Sumo2 5900 is the club that made your buddies cover their ears in 2007. That square head produced a metallic clank on impact that you could hear three fairways over, and plenty of golfers couldn't get past it. Their loss. Underneath the noise was one of the most forgiving drivers of its era, and honestly, one of the most forgiving of any era.

The name tells you what Nike was chasing. Sumo stands for Super Moment of Inertia, and 5900 is the actual MOI number in grams per centimeter squared, which sat right at the USGA's legal limit at the time. Nike threw out the traditional teardrop shape entirely and built a square 460cc head because the geometry let them push weight into the far corners. The result was a driver that flat out refused to twist on off-center hits.

Almost twenty years later, the Sumo2 5900 is a curiosity you can find used for less than a dozen premium golf balls. If you slice everything and don't care what your driver looks or sounds like, it still does the job it was built for. Just don't expect it to keep up with modern heads on raw ball speed.

• Slicers who need maximum help squaring the face, since the extreme MOI keeps mishits from curving into the next fairway.
• Bargain hunters who want proven forgiveness for under fifty bucks on the used market and don't need modern ball speed.
• Anyone building a beginner or backup set where consistency off the tee matters more than looks, sound, or resale value.

Frequently Asked Questions

Is the Nike SQ Sumo2 5900 still worth playing today?

For beginners and high handicappers on a budget, yes. The forgiveness holds up well because MOI physics hasn't changed. What you give up is ball speed, since modern faces are hotter and modern heads are more aerodynamic. Figure you're leaving 10 to 15 yards on the table against a current driver, but hitting more fairways than you would with an older teardrop head.

What does the 5900 in the name mean?

It's the club's moment of inertia, measured at 5900 grams per centimeter squared. That was the maximum the USGA allowed when the club launched in 2007, so Nike was advertising that they'd hit the legal ceiling for forgiveness. Higher MOI means the head resists twisting on off-center strikes.

Why is the SQ Sumo2 so loud?

The square shape and thin crown structure turned the head into something like a bell at impact. Nike moved so much material to the corners for forgiveness that the remaining structure vibrated loudly. Later square drivers from Nike quieted things down, but the original 5900 has a sharp metallic clank that people either laugh about or hate.

Is the Nike SQ Sumo2 5900 legal for tournament play?

Yes. It was designed to sit exactly at the USGA MOI limit, not over it, and it remains on the conforming list. You can play it in club championships and sanctioned events without an issue.

What's the difference between the SQ Sumo and the SQ Sumo2?

The standard SQ Sumo kept a conventional rounded shape with a lower MOI around 5300. The Sumo2 is the square one, pushing MOI to 5900 for more forgiveness. The square version is more stable on mishits but louder and, for some players, harder to look at over the ball. The rounded Sumo was the choice for better players who wanted some workability.
