The power behind the LTDx irons begins at the core. A steel core bar centers the CG behind the hitting zone to deliver maximum power to the ball, and is suspended in a soft polymer to maintain exceptional feel.
More Flexible For More Speed
The PWR-COR system creates our most flexible iron design for increased speed. The construction features a steel core bar that positions the CG behind the hitting zone to transfer more power to the ball. The core bar is fully suspended in a soft polymer to allow the face and sole to flex freely while maintaining exceptional feel.
Longer Distance. Higher Launch.
Our largest PWRSHELL Face increases the zone of maximum ball speed. The new face cup design features a 23% larger thin area to increase speed away from center, and wraps further onto the sole to promote a higher ball flight.
CNC Milled Face And Grooves
CNC milling produces more accurate groove shapes to optimize spin and control for improved accuracy and stopping power into the green.
Tech Overview
PWR-COR TECHNOLOGY
A multi-layer PWR-COR weighting system features a steel core bar that positions the CG low and right behind the hitting zone. The core bar is separated from the face, body and sole and is suspended within a polymer injected casing. The design promotes maximum deformation at impact to create an elastic rebound effect that delivers powerful ball speed.
PWRSHELL FACE TECHNOLOGY
PWRSHELL is a proven technology that has delivered our fastest face designs over the last few product generations. An L-cup face design is forged from a thin and strong stainless steel, and promotes up to 17% more flex resulting in faster ball speed and higher launch across the face.
HIGH MOI DESIGN
Additional mass is positioned in the heel and toe area to improve stability while maintaining a sleeker looking shape that is aesthetically pleasing.
CNC MILLED FACE AND GROOVES
CNC milling produces more accurate groove shapes to optimize spin and control for improved accuracy and stopping power into the green.
