TaylorMade Golf’s SIM2 Max and SIM2 Max OS Irons Deliver the Next Level of Game Improvement Irons Through Cap Back Design

TaylorMade Golf’s new SIM2 Max and SIM2 Max OS irons use the all-new Cap Back Design and evolved ECHO Damping System to deliver unparalleled performance and feel to the game improvement irons.


The industry-leading performance found in the original SIM Max irons inspired the TaylorMade R&D team to ask the question: “What would happen if we supported the entire topline from heel to toe?” Enter Cap Back Design.


In developing this new iron construction, the company charted thousands of shots from players of every skill level – in the process of identifying the most tightly clustered impact areas among solid strikes. Leveraging that data, engineers set out to expand the sweet spot to capture more of those shots, effectively pinpointing performance where golfers need it the most.


Cap Back Design proved to be the key to unlocking this new level of distance and performance. The strong, lightweight polymer material spanning the entire cavity helps to secure the topline and provides additional rigidity in the upper part of the face. It works in unison with the flexible Thru-Slot Speed Pocket™ to create a larger unsupported area of the face, which translates to improved flexibility engineered for increased ball speeds and distance. That added flexibility made it possible to deliver the larger, more intelligent sweet spot.


Beyond added distance and speed, Cap Back Design helped produce a higher MOI with increased clubhead stability at impact to discourage twisting, which allows the golfer to enjoy solid strikes more often. When paired with the ECHO Damping System, the multi-faceted design helps to minimize unwanted vibrations that create the harsh feel associated with traditional distance irons. Producing the signature forged-like feel and sound of SIM irons.


Eclipsing the performance of conventional cavity backs, SIM2 Max and SIM2 Max OS provide a pathway to better forgiveness, distance and feel.


Implementing Cap Back Design allowed TaylorMade engineers to redesign the ECHO Damping System – which features a more concentrated HYBRAR material in SIM2 Max and MaxOS irons. This super flexible insert stretches from heel to toe and is completely encapsulated. The softer polymer blend utilizes multiple contact points across the face to channel away vibrations, further contributing to the forged-like feel while still promoting maximum face flex.



The new intelligently designed sweet spot is strategically positioned to capture the most common impact points, delivering explosive ball speeds and consistency where golfers need it the most. While that added forgiveness is fueled by Cap Back Design, the proven performance of Progressive ICT continues to enhance accuracy throughout the set.


Most game improvement irons have an inherent right-bias, which is why many equipment makers resort to heavy offset to counterbalance the effect. With SIM2 Max and Max OS, however, Progressive ICT gradually shifts the sweet spot toe-ward in long irons to promote a neutral ball flight while also delivering corrective performance on the common right miss.


An array of technologies, such as a fluted hosel, 360° undercut and an ultra-thin face, work in harmony to deliver a low CG that’s engineered to produce a high penetrating ball flight.


Equipped with the same technologies that power SIM2 Max but bundled into a low CG  oversized package, SIM2 Max OS is the longest and most stable iron in the current TaylorMade family. It features a wider sole, stronger lofts and accentuated draw-bias in comparison to SIM2 Max.



Available at retail stores currently, the SIM2 Max and SIM2 Max OS irons (RM5,050 steel/RM4,190 graphite) are offered in 5 to PW and SW (7 pc. set) and come equipped with KBS Max MT 85 steel shafts or Mitsubishi’s Tensei Blue TM60 graphite shafts. For women, the SIM2 Max irons will come equipped with the Mitsubishi Tensei Blue TM 40 graphite shafts and is offered in 6 to PW and SW (6pc set).
