Kirkland Signature Golf Balls are… back?!
Until they sold out of stores, Costco’s Kirkland Signature Golf Balls had the most buzz of any golf ball maybe ever, and they had GolfWRX members going CRAZY. It’s easy to see why; the 4-piece urethane golf balls were selling for only $30 per two dozen, roughly one third of the price of comparable products on the market.
It appears that a new “Kirkland Signature Performance One” golf ball has popped up on the USGA conforming list, updated on March 1.
Based on information presented by the USGA, there are two Kirkland Signature models on the list — “Performance One” and “Tour Performance” — manufactured by SM Global LLC based in Seoul, Korea. The original Kirkland Signature golf balls were stamped “Tour Performance,” but a new “Performance One” is now on the list. According to the USGA conforming list, the Performance One will have a 4-layer construction and 360 dimples just like the original Costco ball.
So, does this mean the Kirkland Signature golf balls will be back in stores? And how much will they sell for? What exactly is different about the new balls? For now, the future is uncertain, but this could be a good sign for fans of the Costco golf balls.

Then and now: Comparing Rory McIlroy’s current setup to his record-breaking 2019 Canadian Open victory
In Rory McIlroy’s first appearance at the 2019 RBC Canadian Open, he crushed the record books to earn his 16th PGA Tour title in dominating fashion, winning by seven shots over Shane Lowry and Webb Simpson.
McIlroy’s score of 22-under-par 258 is the lowest 72-hole score to date at the Canadian Open, and his closing 61 is also the best final-round score in the history of one of golf’s oldest tournaments. Finally, with his win in 2019, McIlroy became only the sixth player to win the career Triple Crown, adding to his victories at the U.S. Open in 2011 and The Open Championship in 2014, joining Tommy Armour, Walter Hagen, Arnold Palmer, Lee Trevino and Tiger Woods in a coveted list.
So, with that, why not compare his current setup to the clubs he used to break all the records?
Driver
2019: TaylorMade M5 (9 degrees), Shaft: Mitsubishi Tensei CK Pro White 70 TX
2026: TaylorMade Qi4D (9 degrees @8), Shaft: Fujikura Ventus Black 7X (45 5/8 inches)
McIroy led the Tour in Strokes Gained: Off-the-Tee in 2019; he’s doing the same in 2026. Between now and then, McIlroy has switched from the Mitsubishi Tensei CK Pro White 70 TX (a shaft with slightly more feeling in the tip) to the original Fujikura Ventus Black 7X, having just made the change to the heavier version from playing the 60X.
What’s interesting about McIlroy’s 2019 setup is that the weighting on his driver is actually set in the high-draw setting, using the T-Track weighting system, whereas in the Qi4D, he’s currently using a heavily rear-weighted setup. (Two 13-gram weights in the rear and only two 4-gram front weights.)
The TaylorMade M5 driver he played in during his Canadian Open win was the company’s first head that they claimed to design to initially exceed the USGA’s COR limit, and then injected with tuning resin to bring it back in bounds.
Fairway woods
2019: TaylorMade M6 3-wood (15 degrees), Shaft: Mitsubishi Tensei CK Pro White 80 TX; TaylorMade M5 5-wood (19 degrees), Shaft: Mitsubishi Tensei CK Pro White 90 TX
2026: TaylorMade Qi4D 3-wood (15 degrees), Shaft: Fujikura Ventus Black 8X; TaylorMade Qi4D 5-wood (18 degrees), Shaft: Fujikura Ventus Black 9X
The TaylorMade M6 fairway wood that McIlroy was using during the 2019 season is still in the bag of some of the best golfers on Tour in 2026. Just check out Justin Rose’s winning setup from the Farmers Insurance Open earlier this year. This year, though, McIlroy has still been searching for his top-end-of-the-bag setup, having played both the new Qi4D and the Qi10, which he won the Masters with.
The same shaft swap can be seen in the fairway woods as the driver, along with slightly less loft on the 5-wood.
Irons
2019: TaylorMade P750 (4) Buy here, TaylorMade P730 (5-9), Shafts: Project X 7.0
2026: TaylorMade P760 (4), TaylorMade Rors Proto (5-9), Shafts: Project X 7.0
The biggest difference between McIlroy’s custom set and the stock P730s is the groove design. While the P730s were constructed with 14 MX-9 grooves on their milled faces, McIlroy’s proto heads instead use the higher-spinning, 16-groove layout of the TW2 grooves. Other big differences between the sets are that McIlroy’s 7- and 8-irons have thinner toplines, are 1 degree stronger in loft, and are 1/4 inch longer than the original P730 builds.
With McIlroy’s 4-iron, the switch from P750 to P760 sees a transition to a two-piece construction with Speed Foam in it, which allows McIlroy to launch the ball slightly higher, with more workability.
Wedges
2019: TaylorMade Milled Grind (48-09SB), TaylorMade MG Hi-Toe (52-09SB, 56-09SB, 60-LB09), Shafts: Project X Rifle 6.5
2026: TaylorMade MG5 (46-09SB, 50-09SB, 54-11SB, 60-08LB @61), Shafts: Project X 6.5 (46-54), Project X 6.5 Wedge (60)
Between 2019 and 2026, McIlroy’s focus on his short game has been much more apparent. It was the reason why he switched back to the TP5 golf ball, to help with launch, spin and control with his wedges leading up to his career Grand Slam victory in 2025. The most apparent changes to McIlroy’s wedge setup are his lofts and bounce. He’s slowly delofted his pitching to a sand wedge, but has increased the loft on the lob wedge, bending his current 60-degree to 61. With that, adding more loft to his lob wedge also slightly increases the bounce and leading-edge sit point, so, as a result, he plays a lower-bounce lob wedge compared to 2019. The MG5 wedges are also softer than the first Milled Grind option from 2019. McIlroy also no longer plays the full-face grooves found on the Hi-Toe.
Putter
2019: TaylorMade Spider X
2026: TaylorMade Spider Tour X
Notice anything similar. Yes, the copper finish on Rory McIlroy’s Spider X putter in 2019 is a slightly more reflective finish than the recently released torched PVD finish. McIlroy was using the True Path alignment system, but now uses only a single white sightline.
Ball
2019: 2019 TaylorMade TP5 (#22)
2026: 2025 TaylorMade TP5 (RORS)
As mentioned above, McIlroy had transitioned from the TP5 to TP5x golf ball since his victory in Canada in 2019, but now is black with the same style of golf ball as his victory at Hamilton Golf & Country Club.
Grips
2019: Golf Pride Tour Velvet Cord
2026: Golf Pride MCC
Interesting, McIlroy actually used Golf Pride’s Tour Velvet Cord grips during his victory in 2019 (it was during a 2+ year switch to the corded TV) as opposed to his usual MCC grips, which he has played for most of his career.

COSTCO always raises they’re prices over time as product becomes more popular….but we all just keep buying so I would bet a million$$$$ prices will be higher and if not right away they will soon be $20/doz not $15/doz

The company that made balls for Taylormade in South Korea may have been replaced by a company in Taiwan…could not find any thing on the web about this..if so that South Korea company is free to make as many balls as Costco can sell?????

I’m confused, the new replacement ball has been tested by the USGA and is on the Conforming List but is exactly the same as the one they previously sold. Was that ball on the Conforming List and if yes, why would an exact ball need to be tested? Oh it’s just a name change, then if that’s correct why aren’t they on the shelves? Sorry I’m always a skeptic.

My club fitter gave me a Ksig to try. I haven’t even messed with it. I’ll eventually check it out when the season is in full swing, but I don’t get all the hype. I’ll still order 5 dozen Vice Pros or Pro +s at the beginning of every season. Not enough incentive for me to bother with Costco or the possible variability of the Ksig. Think about it. If they are in fact overruns of another product and they don’t have their own engineers and such to ensure quality and consistency – who’s to say the ball you played last month will be the same as the ball you play next month?
KillerPenguin
Mar 3, 2017 at 1:25 pm
Because it’s a urethane ball that costs $1.25 a piece. I’m a budget golfer with a bazillion handicap who plays 12 year old irons acquired second hand and am a Costco member so I’m exactly the person who will line up to buy this. At that price, and at my level of skill, I’m willing to roll the dice on consistency between balls. My consistency in squaring the club face at impact is a much bigger issue than the quality of the ball I hit.
TR1PTIK
Mar 3, 2017 at 2:07 pm
So at your skill level and consistency, why do you feel the need to hit a urethane ball? Why not just buy the Wilson Fly for $5/15?
Just playing the devil’s advocate here. No offense. I just think the type of players that truly need that level of playability should also be thinking in terms of consistency and quality. With plenty of other players in the market and so many unknowns (currently) about the development of Ksisgs, why all the fanfare? I absolutely agree that the Titleist premium needs to die and other OEMs seem to recognize that (new Z-Stars @ $39.99/dz and similar pricing from Callaway).
ABLE
Mar 4, 2017 at 9:03 am
I’m with TR1PTIK on this one. If you’re a high handicapper (I can relate, I shoot over 100) then a four-layer urethane ball is a novelty and you really could be playing with used balls. If hitting consistently is your biggest problem, the quality differences between a Noodle, Velocity, Chrome, RocketBallz, Pro V1 and a used ball will be indecipherable. The only difference I can tell between a Velocity and a Noodle or Nike is that my wallet gets lighter when I hit a Titleist into the bush.
Hifade
Mar 3, 2017 at 11:39 am
I’ll bet these new balls are completely different, but Costco is trying to capitalize on the original demand. The first run were balls manufactured with Taylormade cores that TM had left over and unloaded to Costco (like selling scraps). When they were gone…..they were gone. I highly doubt this new version is constructed with the same components.

Probably not. Costco has a tendency to market a single product that goes after the market leader, rather than having four versions. Kirkland isn’t known for its variety within the brand.

Most urethane covered balls are made by big OEM’s in America by American workers. These balls are made in Korea. If you buy these balls, but complain about jobs being lost overseas, you are a HYPOCRITE.

I doubt the price will change much. Think like a retailer. They have these products called advertisement loss leaders. Laymen’s term. Gets people in the door, to spend more money. Costco found out people were buying more than a couple dozen balls. Costco is one of the best at getting people to spend money.

People are talking about which overruns these will be not understanding where golf balls are made, how golf balls are made, and the background of the golf balls history..

Big difference. Titleist doesn’t spend millions on R&D for nothing. They make better golf balls. Choppers may not know the difference but tour professionals do. It all depends whats most important. A somewhat better ball or saving $$$.
Brian

Might not be the same ball as before. Depends on whether they could get their hands on the same components. I thought they were out of the Taylormade cores.

My guess is that Taylor Made felt “Tour Performance” was too close to “Tour Preferred” so they had to relabel it. Hopefully the ball itself is the same

LaBraeGolfer
Mar 3, 2017 at 8:26 am
I have a feeling they are going to sell the comparable ball for a lot more and then the ball that is the same price as the old one will be a two piece distance ball. I hope I am wrong, I would like to try them if I stop in while they have them.
baba black sheep
Mar 3, 2017 at 9:01 am
I’ll bet you’re right. Rather than just jacking the price up to where it should be on the Tour Performance ball they probably just had the manufacturer stamp Performance One on it so they can sell it for more by calling it a newer and better ball.
Scott
Mar 3, 2017 at 9:18 am
Maybe you did not see the chart at the bottom. Both balls appear to be 4 Piece. I am not sure what the “SC” means for the Tour Performance ball. Soft Compression maybe?
Lopey
Mar 3, 2017 at 10:24 am
SC means Solid Core.
They aren’t going to jack up the price. They’ll make them membership only and use it to sell memberships. They do this with a lot of products. Sell them at cost and make no profit but use them as leaders to sell memberships.

Mar 3, 2017 at 11:45 pm
…So far, they seem to be pretty smart with their other offerings. They aren’t losing money on these, and they made the entry at a time when the “regular” golf market was generally depressed….Dick’s eliminating the PGA pros & shrinking the sqft in golf, Nike quit…I doubt they’re looking to jump in much beyond this and risk mission creep….just like when NIKE SWORE TO US – absolutely swore they’d “never end up like Top Flite”. “We’re just going to have these two premium balls (DD & TW) one mid-price and one soft”… keep it simple and they’ll do fine.
