How many distance irons can say they have their own sound engineer? With an improved Speed Bridge and ECHO Damping System for better sound and forged-like feel, TaylorMade went further than they thought possible to bring you a distance iron that feels better than anyone thought possible. A more refined Speed Bridge puts SIM Max OS a step above its predecessor, and the ECHO Damping System expands across the entire face from heel to toe, giving you forged-like feel in a distance iron. The new SIM Max OS irons have a 8% thinner face than the previous class, increasing ball speed and forgiveness. The Thru-Slot Speed Pocket completely disconnects the lower portion of the face from the sole of the iron and allows for a free-floating face. When combined with Speed Bridge, the face maintains stability while delivering maximum ball speed. An oversized construction results in a larger sweet spot and more forgiveness across the entire face. SIM Max OS delivers the most distance of any iron in TaylorMade's 2020 lineup. If you would like to customize the shafts, grips, lengths or lies give us a call or send an email to Tom@dallasgolf.com. Standard TaylorMade warranty applies and satisfaction is guaranteed.
