These hollow iron-wood designs put a major emphasis on ease of launch, playability and correcting miss-hits and slices to go straighter for the ultimate ease of use. The improved hollow-body design of the Hot Launch E524 Iron features the game-changing Houdini Sole in conjunction with a super-shallow face, slice-fighting offset designs and heel weighting for added draw bias.

Houdini Sole Technology – The Houdini Sole is a raised steel mass area at the rear of the clubhead, as well as a curved leading edge under the face. The patented Houdini Sole reduces the amount of sole area to reduce drag and turf interaction by 35% and is instrumental in significantly altering the CG placement of the E524 Iron, making it one the highest launching and easiest to hit irons ever produced.

Hollow-Body Perimeter Weighting - Hollow-body perimeter weighting produces distance properties of a metalwood in an ironlike design. Hollow-body perimeter weighting produces maximum ball speed off an iron. The hollow body design makes for an extremely low and back CG, helping to create a very forgiving and powerful face.

Shallow Face / Offset Design - The super-shallow face coupled with an offset design are designed for extreme playability and high-flying launch characteristics. The offset design acts as built-in slice fighting technology, squaring the clubhead at impact to produce anti-slice ball flights. The extremely shallow face produces higher launch angles and extreme ease of launch with extreme forgiveness.

New 524 Shaping - New shaping on the 524 Iron includes a wider front to back length, a thinner top line and more weight located lower in the clubhead. What does it do? The lower Center of Gravity in the 524 design leads to a higher MOI that brings more forgiveness and stability to the clubhead, and also increases launch characteristics to make it easier to get the ball in the air.

Ultra-Light Premium Shafts - The E524 Iron comes stock with an ultra-light ALDILA ASCENT PL (Performance Light) graphite shaft. It is also available in a True Temper Elevate MPH 95 steel shaft as a stock option. The ALDILA ASCENT PL provides lightweight performance with faster club head speeds without sacrificing feel. ASCENT PL technology is designed to resist ovaling, keeping the club head in position and creating more center-face contact. ALDILA ASCENT PL is best for golfers seeking lightweight performance and additional speed without sacrificing stability.

The True Temper Elevate MPH 95 steel shaft is designed to combat the low spin industry trend. Elevate MPH (Maximum Peak Height) is the lightest and highest launching Elevate shaft ever made, allowing for maximum speed and carry distance.
