Tour Driver

The TSi4 is the driver Titleist built for players who spin the ball too much and want the smallest margin between a good swing and a great one. At 440cc, it sits well under the 460cc limit that most drivers chase, and that compact shape tells you exactly who it's for. This is a low-spin head aimed at fast swingers who deliver the club consistently and don't need the head doing extra work for them.

The whole point of the TSi4 is spin reduction. Titleist moved the center of gravity low and forward, which knocks RPMs off the ball flight and produces a flatter, more penetrating launch. For a player carrying too much spin off the tee, that change alone can add real distance and take the ballooning miss out of play. The tradeoff is honesty: a 440cc head with forward CG is less forgiving than its bigger TSi2 and TSi3 siblings, and it doesn't hide a bad strike.

It's adjustable through Titleist's SureFit hosel, so you can dial loft and lie to fine-tune launch and shape your bias. But adjustability won't turn this into a game-improvement driver. The TSi4 is a specialist tool, and if you're the swing speed it was made for, it rewards you. If you're not, the TSi3 is almost always the smarter pick.

• Fast swingers, usually 105 mph and up, who generate more spin than they want off the tee
• Players who strike the center of the face consistently and don't need extra forgiveness from a larger head
• Better ball-strikers chasing a flatter, more penetrating flight that cuts through wind
• Golfers who want to shape shots and control trajectory rather than launch it high and let it ride

Câu hỏi thường gặp

What's the difference between the TSi4 and the TSi3?

The TSi4 is a 440cc low-spin head with a forward CG, built for high swing speed players who spin the ball too much. The TSi3 is the full 460cc and launches a little higher with more spin and forgiveness. Most golfers are better off with the TSi3. The TSi4 is the pick only if your spin numbers are genuinely too high and your strike is reliable.

Is the TSi4 forgiving?

No, and it isn't meant to be. The smaller 440cc head and forward center of gravity give it a tighter sweet spot than the TSi2 or TSi3. Off-center hits lose more ball speed than they would with a bigger, higher-MOI head. This is a driver for consistent ball-strikers who want spin control over forgiveness.

What swing speed do you need for the TSi4?

It's aimed at faster swingers, generally around 105 mph and up with the driver. The low-spin design helps most when you already produce plenty of spin from speed. Slower swingers usually need more spin to keep the ball in the air, so they tend to lose carry with a head like this.

Can you adjust loft and lie on the TSi4?

Yes. It uses Titleist's SureFit hosel, which lets you change loft and lie independently to fine-tune launch, land angle, and shot bias. That flexibility helps you get the low-spin flight dialed in, but it won't make the head more forgiving.

Why is the TSi4 only 440cc instead of 460cc?

The smaller head is part of how it lowers spin. A compact 440cc shape with a low, forward center of gravity produces a flatter, lower-spinning launch than a full-size 460cc head. You give up some forgiveness for that spin reduction, which is the exact trade this driver is designed around.
