Costco has a weird habit of breaking the internet every time they change their golf ball packaging. It’s almost a ritual now. You walk into the warehouse for a rotisserie chicken and leave with a 24-pack of the Kirkland Signature Performance+, wondering if you just bought a Pro V1 killer or a high-spinning marshmallow.
The newest version of the Kirkland ball is officially here. But if you’re looking for a giant "Version 4.0" on the box, you’re out of luck. Costco is still calling these "v3.0," which is confusing as heck for everyone involved.
Honestly, the "new" ball is more of a v3.5. You can spot it by the hollow alignment arrows on the side stamp. The older ones had solid chevrons. It’s a tiny detail, but for gear nerds, it’s the difference between a ball that balloons into the wind and one that actually pierces the air.
Why the New Kirkland Golf Balls Actually Matter
For years, the knock on Kirkland was the spin. They spun too much. Like, "holy crap I just sliced that into the next zip code" levels of spin.
If you weren't a high-speed ball striker, the old Kirkland was a disaster off the tee. It would climb into the sky, stall out, and drop 20 yards short of where a Titleist or TaylorMade would land. The new iteration has finally addressed this, mostly.
Costco bumped the compression up. MyGolfSpy’s recent testing put the new Performance+ at a 97 compression. That is firm. For context, a standard Pro V1 usually sits around 91. You’re getting a ball that feels closer to a Pro V1x or a Bridgestone BX.
It feels "clicky." Some guys hate that. If you like the feeling of hitting a sock, this isn't your ball. But if you want feedback and a bit of "thud" off the putter face, you’ll probably dig it.

The Real World Numbers
- Driver Speed: It’s faster. The higher compression means it doesn't deform as much for the big hitters.
- Long Game Spin: It's down. Not "low spin" by industry standards, but significantly lower than the previous silver-stripe box version.
- The Wedge Factor: This is where the ball still wins. You’re getting a urethane cover for about $1.25 per ball. It bites on the green.
I’ve seen guys at the local muni drop a Kirkland on a 40-yard pitch and watch it one-hop-stop just like a $5 ball. It’s impressive. It’s also why these things are constantly out of stock or being resold on eBay for a markup.
The Durability "Issue"
Let's be real: the covers used to be fragile. You’d hit one well-struck wedge and the ball would look like it had been through a cheese grater.
The 2025/2026 batches have improved the cover resilience. It’s still not as indestructible as a Surlyn-covered "distance" ball, but you can actually play 18 holes with one now without it looking hairy by the turn. Unless you hit a cart path. If you hit a cart path, no amount of Costco engineering is saving that urethane.
The Yellow Ball Mystery
Costco also refreshed the Neon Yellow version. It’s the same 3-piece construction, but the color is… interesting. It’s very bright. Almost a "high-vis" green-yellow that stands out in the rough.
Some players have noted that the yellow version feels slightly different off the face—maybe a psychological thing, or maybe a slight variance in the coating process. But on the launch monitor, the data is nearly identical to the white version.
Is It Actually a Pro V1 Killer?
No. Stop. Let's kill that narrative right now.
A Titleist Pro V1 is the most consistent ball in the world because their quality control is insane. If you buy a dozen Titleists, all 12 are going to be identical. With Kirkland, the tolerances are wider. You might get one ball that’s a fraction off-center in the core.
But for a 12-handicap? You won't notice. You’re not good enough to notice a 200 RPM variance in spin.

What you will notice is having an extra $30 in your pocket after your round. That’s the "Kirkland effect." It’s about 85% of the performance of a Tour ball for 30% of the price.
How to Buy the Right Ones
Don't just grab the first box you see. Look for these specific markers to ensure you're getting the updated 2025/2026 stock:
- The Red Stripe: Look for the black box with the red vertical stripe. Avoid the older silver stripe boxes if you find them lurking in the back of the pallet.
- The Side Stamp: Check the "Performance+" text. If the arrows on either side are hollow outlines, you’ve got the new stuff.
- Price Check: These have crept up in price. While they used to be $24.99, most warehouses are now charging closer to **$29.99 to $34.99** for the two-dozen pack. Still a steal.
If you’re a high-spin player who already struggles with a slice, this ball might still be a bit "active" for you. It wants to spin. But for the average golfer who needs help stopping the ball on the green, it’s arguably the best value in the history of the game.
Next Steps for Your Bag
Check your local Costco’s inventory via the app before driving out there. If you’re a high-swing speed player (105+ mph), buy one box and test it against your current ball on a launch monitor to see if the driver spin stays under 2800 RPM. If it does, you just found your new gamer. If you find the ball ballooning or falling short on windy days, stick to a lower-spin premium option for your competitive rounds.
