TaylorMade RocketBallz HP 4-PW, AW Iron Set with Steel Shafts

The first distance iron to make it on tour, TaylorMade RocketBladez HP Irons are powered by the Speed Pocket. This little thing has changed the iron forever. Only RocketBladez HP are powered by the Speed Pocket to promote radically increased speed and distance. This revolutionary technology is engineered for optimum face-flex, creating a consistent and stronger ball flight. RocketBladez HP are the true blend of the finesse the pros demand and the explosive distance amateurs crave. Get them or get left behind.

Inspired by the distance-enhancing benefits of the RBZ Speed Pocket technology that makes RocketBallz fairway woods and Rescues so fast and long, TaylorMade engineers found a way to incorporate a Speed Pocket into irons. The result is a once-in-a-lifetime innovation that revolutionizes iron performance not only in terms of distance, but also distance-control and feel.

The RBZ Speed Pocket in RocketBladez HP irons flexes and rebounds at impact, increasing the speed of the face to promote faster ball speed and a higher, stronger ball flight that lands on a steep, quick-stopping descent angle. This Speed Pocket advantage is especially effective on impacts made low on the face, TaylorMade studies indicate that 72% of iron shots hit by amateur golfers are struck below center face.

The RBZ Speed Pocket in all RocketBladez HP iron models is filled with a Polyurethane Reactive (PUR) made by 3M that keeps out debris and dampens unwanted vibration while still allowing the slot to flex at impact.

The RBZ Speed Pocket, in conjunction with the highly sophisticated face design (11% thinner than TaylorMade's previous thinnest), adds up to 10 COR points to the face compared to Burner 2.0 irons, and promotes dramatically less drop-off in ball speed on impacts low on the face-where the majority of iron mis-hits occur. That means the COR low on the face is higher than it's ever been in a TaylorMade iron, and the benefit is that thin shots carry significantly farther.

The RocketBladez HP clubface consists of strong, maraging stainless steel. It is TaylorMade's most sophisticated clubface design yet, made possible by more evolved analysis and testing and their increasing mastery of the manufacturing processes. It's the thinnest iron face they've ever created, with the top section now 1.6 mm, down from 1.8 – that's 11% thinner. RocketBladez irons also incorporate their newest and most effective iteration of Inverted Cone Technology. The improved Inverted Cone design delivers two critical benefits. One, it increases the size of the clubface area that delivers high ball speed. Two, it influences how the face flexes and rebounds at impact to control the angle at which the ball leaves the face, promoting straighter shots and a tighter dispersion. This is a critical benefit that promotes significantly greater accuracy compared to previous high COR irons.

Impacting the ball where the CG is located on the face is critical to achieving maximum ball speed. In RocketBladez HP irons, TaylorMade engineers fine-tuned the CG to a low and absolutely centered location on the face by shortening the hosel to save weight and taking additional weight from the top of the club, then redistributing it all in strategic areas within the head. In the RocketBladez HP clubhead design, 17.5 grams of redistributed weight enabled us to lower the CG by 2.5 mm compared to the Burner 2.0 iron. Locating the CG lower and in the center of the face makes it easier to consistently find the sweetspot to achieve maximum energy transfer from club to ball, promoting a higher launch angle and maximum distance.

RocketBladez HP irons feature a distinct external notch on the outer, rear side of the hosel and an internal notch inside that together make it easy to bend the head to change the lie angle. That's a distinct advantage to bendability when employing high-strength stainless steel in the head construction.
